LCDProc 0.5.4-dev

mdima

Hello everybody,
I just updated the package. The news are the following:

Fix the uptime screen
In the settings, "Enable LCDproc" becomes "Enable LCDproc at startup"
Added "After Install Info" message
Limited the client loop to three times. After three errors connecting to the LCDd service the client will end

I hope the 4th point will solve the problems for the Firebox boxes! Just wait for the 0.9 version of the package and update it…

Thanks to all for the feedbacks,
Michele

EDIT: With a feedback, please post the driver/port you're using, the values of the options of the service and the list of the screens active, thanks!!

Hello,

can I leave the LED backlight on all the time? Is this implemented in this update?
Or will it come in a future version?

@power_matz: The backlight control is part of the driver not the package so this won't have changed.

@mdima: Awesome work! ;D I can't wait to test it.

We are currently focusing on fixing the issue of multiple instances of the server, as well as building the code for driving the LEDs. Once that is stable, we can revisit the user parameters.

Well the update didn't help for me… :(

48731 nobody    74  r30  3368K  1488K RUN     77:11 100.00% LCDd

Running clog of /var/log/system.log showed no entries related to the LCD processes.

However it DID continue to work properly this time although the screens changed about every 7 secs or so instead of 5 secs with the webif non-responsive and new SSH sessions not completing to connect. Existing SSH sessions continue just slowly as expected under the load.

For reference all my settings for the Firebox x700 are "default" with "2x20 columns" and the SDEC driver on /dev/lpt0. The only screens enabled are: Uptime, Load, States, Mbuf, & Interface Traffic (WAN).
GW monitoring is disabled.

EDIT: Forgot to add

like the new Uptime screen! Much cleaner.
in my set up, it seems to be failing after around 16-18 hours uptime and/or around 4-5am, not sure which yet, with no network activity occurring.

Hi Tix,
thanks for the info! I am now running my secondary machine with the same screens in order to test the "client" part of the package. If there is something wrong in the client for this screens I will find out soon. Of course I can only test the client because I use a different driver… but if the test goes OK it means some problem in LCDd 0.5.5 or the driver.

Thanks for apreciating! I will see tomorrow how my secondary machine is doing…

You think you can program more stuff on the LCDproc MENU?

Maybe stuff like webGUI restart, backup config, restore config, reboot system

Thanks! Doing an awesome job!

To all, I am using GWXepc for the Arm/Disarm LED to turn it green when pfSense comes up and red when it goes down.
What I did was edit the beep.sh and in "start" I added GWXepc -l green and in "stop" I added GWXepc -l red

I've now been running 0.54 versions of LCDd and sdeclcd for 24hrs and am still experiencing the same LCDd CPU usage lock out. So I think we can rule out going to 0.55 as a problem.
Interestingly I was able to observe it happening this afternoon and it ramps up slowly as if it's looping around creating steadily more and more processes until it hits 100% cpu.

One way to test this would be to compile the old driver against 0.55 and run that. I don't have a suitable compile environment setup at the moment though.

Steve,
how many instances of the client were running at that time? Do you have any log that evidence problems or concurrent clients running in the same time?

Thanks,
Michele

stephenw10

Hmm, I'm not sure what you mean.
There were two distinct problems I experienced.
Firstly where multiple copies of the client ended up running. This happened immediately after either rebooting or restarting the service.
Secondly where LCDd ends up using 100% cpu. Just one client can be running when this happens.
I don't have much by way of logging. Can we increase the logging level in lcdd.conf?

Ok, but thanks to the last change the "second client" was stopped after 2 more attempts to connect, I guess.

Ok, that's awesome. At least we know that the issue is not related to multiple instances of the client running, which in any case should not give any problem (since LCDd is made to support different clients in the same time), but for sure it is not a "resoruce leak" because of the PHP client bothering the system…

Thanks,
Michele

stephenw10

Yes I agree two distinct situations.
The first should have been solved by your recent update, thanks!
Though as you say LCDd can support multiple clients. Interesting though that this doesn't arise with any other driver even though it should not happen.

@jpsb:

I just use the HD44780 in the driver list, and by connecting the display, the system log shows "LCD2USB device found"
The display is a little slow, and works best by refresh frequency on 5 or 10 sec.

Hi JPSB,
mmhhh… seems strange... how many screens you have active? Did you have the same problem also with the previous version?

Thanks,
Michele

Hi Michele

Yes I had the same problem with last version.
I only have "Interface Traffic" and "Load" running.
But the new version with options to change contrast, etc. makes the display is running perfectly.
I have not had any luck getting the new driver "hd44780 Fast" to run.
But as I said, it runs perfectly with the other changes.
So once again, many thanks for a fantastic job.

See my youtube video of the display:

Hi I having problem with the display running on the alix2d13 hardware.
After about 12 hours, the CPU load runs at 100%, and Pfsense freezer.
I have tried with multiple modules loaded but it makes no difference.

PFSense 2.0.1
alix2d13
4Gb CF-card
MiniPCI vpn1411 encryption accelerator
U204FB-A1 20x4 Display

What if we roll back to 0.5.4 (now the package works with 0.5.5)??

stephenw10

I've been testing using 0.54 versions of LCDd and sdeclcd.so and there is no difference. As I type this I'm unable to access my box.
The fact that jpsb is experiencing a similar problem with a different driver is alarming.

I haven't tried going back to pfSense 2.0 yet. :-\

Still testing…

Steve,
can you try to use the LCDproc package (I mean not the "-dev" package) and see if the problem occurs?

I guess with the "LCDproc" package you didn't have any problem or you were not running it?

Thanks,
Michele

I don't know if it can help, but some time ago I had a endless startup processes from mailscanner that exausted machine resources every boot.

I noted that at bootup, mailscanner startup was called several times.

May be there is something related with multiple lcdproc scripts/prccess opened.

Thanks Marcello, but for what I understood it is the only LCDd process that after a certain amount of time eats all the resources…

I never ran the original LCdproc package (except while trying to develop my own package and then only for a few hours) because it never included the sdeclcd driver.
Before you added the driver to the LCDproc-dev package all firebox users were running a manual installation that consisted of:
LCDd 0.53
lcdproc client with manual command line options for screens.
The old sdeclcd driver.
A simple startup script that ran the server and client once from /usr/local/etc/rc.d

I never saw this crash out on any box. It was distributed as a tarball with an install script. Here.

I never tested this with pfSense 2.0.1.
