      Did you updated dansguardian binaries after 2.12.0.3 to fix web upload bug?

          Marcelloc, yes I did try the package in this thread http://forum.pfsense.org/index.php?topic=58442.0 however it did not resolve the signal 11 issue.

            I'm thinking about just rolling the Dansguardian package back to 2.12.0.0 however I do not see a tbz for this version under files.pfsense.com anyone know how I might roll this version back or how to install an older PBI?

              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.

                                  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
