      I have a feeling that's because every time pfSense detects an IP change on an interface it restarts all the packages.
      I think it may be caused by trying to start a new instance of LCDd before the old one has been killed. LCDd then cannot open local port 13366 and quits leaving lcdclient.sh running and spamming the logs. In the worst case this happens several times with the result that several instances of lcdclient are running.
      Perhaps this is caused by the sleep delay in between the kill statements? Perhaps it should kill LCDd first?  :-\

      In my opinion lcdclient.sh needs to quit after, say 3, tries if lcdproc_client.php cannot connect to LCDd. Is that what Seth had in mind when he setup the counter variable in lcdclient?

      What do you think?

        Hi Steve,
          yes, I agree… I will do this improvement in the next update of the package...

          I tried this LCDProc 0.5.4-dev and all it does is flash a few screens real fast then it says "Thank you for using pfSense" and sits on that screen forever…  :O

            Could you show us your system logs?
            I suspect you are seeing the same as me. Is that on your X-Core box?

              Hi m4f,
                Did you set all the new properties in the service configuration?
              Can you tell me what values did you enter?

              Thanks,
                Michele

                Steve: Yes, it's on the X500 (I also have an X700 but they are the same hardware)

                Hrm!   I had uninstalled it, when I installed it again it installed 0.5.5 v 0.8   :O

                Here are my settings:

                Under Server tab:
                Enable LCDProc: checked
                Com Port: Parallel port 1 (/dev/lpt0)
                Display Size: 2 rows 20 columns
                Driver: Watchguard Firebox with SDEC (x86 only)
                Refresh frequency: 5 seconds
                The rest are set Default and the LED option is disabled

                Under Screens tab I have enabled:
                Version, Time, Uptime, System, Disk, Load, States,
                Load Balancer, Interfaces, CPU Freq and Internet Traffic

                        mmmhhh… I am trying to mess it up as much as I can, but really, after every try I only get 1 server and 1 client running (also with enable/disable of ipsec that foces a package resync)... with:
                        Refresh: 1 second
                        Driver: sureelec
                        Screens: ALL

                        I don't even find the problem on the stats and time screens, both from a machine running since 31 days or a machine just booted...

                        Anyway, I will change the package in order to let the client make only 3 attempts to connect to the service then quit...

                          I appreciate all your efforts, thanks.  :)

                          It's looking like a driver issue is more likely then.
                          There seem to be two issues here:
                          1. When the package is started/restarted in quick succession some delay in the process can result in LCDd trying to start before the previous version has stopped. Or possibly the previous version simply does not stop as I have found when trying to kill it manually.

                          2. The LCDd process can start to use a lot of CPU time causing the box to become unresponsive (but still routes traffic OK).

                          For testing purposes we can either:
                          Build the old driver against 0.55 or
                          Swap out LCDd with a 0.54 version and equivalent driver.

                          What do think? I may have 0.54 version files the fmertz mailed to me. I'll try that if I do.

                          Steve

                            Well, a driver is a shared library. It is coded so there is just one copy of the code between multiple instances of LCDd server. For instance data, everything is dynamically allocated, so each instance behaves independently. Obviously, as there is just one set of interface ports, and one LCD, this flexibility is not necessarily helping. I think fixing the multiple instances of the server will go a long way towards fixing these problems. I can look at the code again to see if I can fail initialization on second instance and up. Let me know if I can help compiling anything.

                              I have just acquired an x700 from work and trying to get it running smoothly and am encountering this problem.  It is a clean full install (on HDD) of 2.0.1 with IPv6 git sync'd as of 21 Jan.
                              I keep running into this within 16-24 hours uptime where the system is non-responsive but still routes although more slowly than normal.  I cannot SSH use the webif, or console when this happens.  The RRD graphs stop as well.  I have only the load and states screens enabled thinking maybe the number of screens was an issue, but today when it became unresponsive it was stuck on the load screen and the current load was displayed as a 24.4!!!

                              I am also of the (pretty much worthless) opinion that it is too many instances of the LCDProc client as I can see the log entries posted above.  I am going to disable LCDProc-dev for now and see if everything stays stable for at least 24 hours.

                                  The more people running this and giving feedback the faster it's likely to be solved. So thanks.  :)
                                  If you are running it again try to SSH in. After you enter the password it appears to have frozen but if you wait long enough it will log in (several minutes). Then you can see what's running. E.g.

                                  You should see one instance of each of those three programs running. If you have more then it has started or stopped incorrectly.

                                  You can also run```
                                  top -SH

                                  LCDd should be consuming 1% or less cpu.

                                      The more people running this and giving feedback the faster it's likely to be solved. So thanks.  :)
                                      If you are running it again try to SSH in. After you enter the password it appears to have frozen but if you wait long enough it will log in (several minutes). Then you can see what's running. E.g.

                                      You should see one instance of each of those three programs running. If you have more then it has started or stopped incorrectly.

                                      You can also run```
                                      top -SH

                                      LCDd should be consuming 1% or less cpu.

Steve

                                      Thanks Steve but I've tried that and even after more than an hour I still cannot get the menu so I usually give up and do a power-cycle as that is the only way I've found to recover.
                                      I would love to be able to confirm if there are multiple instances as well as memory usage and such but so far that is not an option.

                                      I forgot to mention previously that someone had suggested that when the connection drops that all the packages are restarted so I disabled the gateway monitor but that made no difference.

                                      The next time I get to watch it for a full day (next weekend?), I will keep an SSH session up running top and hopefully capture some useful information.

                                      EDIT:
                                      One more thing:  The looking at the RRD graphs (processor, memory, & states), there is nothing indicating an increase in processes or utilization.  Everything is "normal" and then just stops graphing until I reboot.

                                          I turned LCDd on overnight and left my SSH sessions active running top -SH
                                          This morning I have an unresponsive machine except the SSH sessions are still active.  (Also, everyone was asleep so there was no usage from LAN to WAN.)

                                          I killed the LCDd process after capturing the information below and load drops to less than .10 but I cannot restart it.  If I use the webif it will generate the previously mentioned log entries and the same occurs starting it from the CLI.

                                          top -SH

                                            Further confirmation of a problem. Thanks.
                                            By the way pfSense uses circular logs so you have to use clog to tail them.
                                            See: http://doc.pfsense.org/index.php/LOGS:Why_can%27t_I_view_view_log_files_with_cat/grep/etc%3F%28clog%29
