      Nevermind I just downgraded Dansguardian to 2.12.0.2 and it is working without an issue. Seems like there is a problem with the 2.12.0.3 package just an FYI.

        I'll try to compile latest alpha version to do some tests.

            Marcelloc, I'd like to install the 2.12.0.5 version of Dans Guardian as the sites that I support
            are both experiencing the Signal 11 issue with Dans Guardian.
            The sites are running 2.12.0.3 v.0.1.8 with your patched DansGuardian binary (to enable web uploads)

            I see that the new version that you have made available  is a .tbz file which looks like the complete package.

            How do I install this over an existing running copy of DG?
            Is it a simple case of pkg_add dansguardian-2.0.5.tbz?
            Do I need to uninstall DG first and if so what happens to the current configuration files (lists, groups etc)?

            Thanks
            Neil

            ???

              pkg_delete current dansguardian package and then pkg_add -r with full url path.

              If you are using squid3, then check if dansguardian install process forced squid2 install. If so, reinstall squid3.

              And let me know if signal11 is gone on your install with this version.

                    Cheers,

                    It seems to require squid 3.4 among other things.

                    Anyway, I get the follwing error when starting it.

                    Config problem; check allowed values for pcontimeout
                    
                    

                    Yet to find an error in one of the conf files… I presume its complaining about the proxy connection timeout value... but that's set to 30 by default anyway.

                      oops, seems dansguardian needs three new values in the conf file come 2.12.0.4

                      # Proxy timeout
                      # Set tcp timeout between the Proxy and DansGuardian
                      # Min 5 - Max 100
                      proxytimeout = 20
                      
                      # Proxy header exchange
                      # Set timeout between the Proxy and DansGuardian
                      # Min 20 - Max 300
                      proxyexchange = 20
                      
                      # Pconn timeout
                      # how long a persistent connection will wait for other requests
                      # squid apparently defaults to 1 minute (persistent_request_timeout),
                      # so wait slightly less than this to avoid duff pconns.
                      # Min 5 - Max 300
                      pcontimeout = 55
                      

                      First signs are promising, no sig 11 yet.

                        Well, so far a child process hasn't dropped out, however I now have a load of ntlm failed auth's?

                          Do you have ntlm auth set? I'ts working and logging some failures or it's not working?

                          This version is compiled for high load, do you think it's running faster?

                              I do have ntlm auth set, did have it in conjunction with basic, but it doesnt seem to matter if thats enabled or not.
                              NTLM auth is working, I am getting usernames in the logs, nobody has complained they cant get on yet… I wonder if its a piece of software attempting to auth..

                              Well, it seems marginally faster. Still getting the occasional redirect not being followed. I have all the tunables in the dansguardian.conf set for "suggested for large site" settings.

                              I wonder if I should upgrade squid.

                                well, that worked yesterday (despite the ntlm auth errors), but today we are back to the same signal 11's.

                                I have gone back to 2.12.0.2 for now.

                                  I also have some of these errors - although it sounds like you're seeing it more often. I did a little googling and it seems that this issue with DG under freeBSD has existed for a long time. I didn't find any definitive answers, but most suggestions for fixing it centered around changing the DG settings - such as max children, max spare children, and max age of children. I bumped some of these settings up yesterday and will let you know the results…

                                    With the latest version you can adjust maxchildren (maximun value) with your system
                                    For example on linux :

                                    ulimit -n 8192 -> new ./configure option = with-filedescriptors=8192 = dansguardian.conf maxchildren=8192

                                    Maybe this is a clue ? Perhaps this version was compiled with too much high value for the system ? Can you play with ulimit ?
                                    How many process are running when the crash appear ? ps -edf | grep dansguard | wc -l

                                      Well you can adjust the max/min children in the conf file, but it didn't seem to make much difference, same config file with the previous version (minus the bits added for that particular version) works. I'm afraid I cant count the processes, rolled back to 2.12.0.2 and don't currently have a dev box running only production.
                                      If I get a chance I will run up a vm for it "later"

                                        Yea, I'm still having he problem. About ever other day I get a half dozen or so DG processes ending with signal 11. Are you saying one of the versions doesn't do this? If so, which one?

                                          Signal 11 means that the program accessed a memory location that was not assigned to it, the strange thing that there is no problem in Linux (with dansguardian 2.12.0.5)

                                          Please, Can you post your maxchildren value ? More than 1024 ?
                                          And if someone know the value of FD_SETSIZE in types.h (or posix_types.h) and typesizes.h with FreeBSD ?
                                          Also can you post the compilation option (dansguardian -v)

                                          No problem at all with 2.12.0.2 ?

                                          Thanks

                                            Based on some notes here http://contentfilter.futuragts.com/wiki/doku.php?id=faq (see FAQ 26b)
                                            I have bumped the following sysctl values (in loader.conf.local):
                                             kern.ipc.shmseg=512
                                             kern.ipc.shmmni=512
                                             kern.ipc.semmni=512
                                             kern.ipc.msgssz=64
                                             kern.ipc.shm_use_phys=1

                                            at the moment, I have maxchildren set to 120 and maxsparechildren at 48
