Re: [rt-users] Regarding Apache server failure
Hi Matt, Thanks for posting this, Yes I was able to get the solution. The issue in my case was I missed one of the key plugin and Apache didn't show me that missing plugin in logs, later when I set the RT log then i was able to found it. Thanks, Bharath.

Re: [rt-users] Regarding Apache server failure
Hi Bharath, Were you able to get a solution to this? I just upgraded to Ubuntu 14.04 (from 11.04) and am experienced this same issue. Your post actually helped me localize it to the external auth plugin. I found that I was running and older version (0.20) of the plugin. When I upgraded to version 0.25, the issue went away. Thanks, and hope that helps you. -Matt On Thu, Oct 8, 2015 at 11:48 AM, bharath reddy wrote: > Matt, > > I don't think it is a problem with RAM or any hardware, because when I > revert my changes in RT_SiteConfig.pm (with out LDAPAuthentication) apache > starts with out any error. > > Thanks, > Bharath. > > On Thu, Oct 8, 2015 at 10:54 AM, Matt Zagrabelny > wrote: > >> On Thu, Oct 8, 2015 at 9:21 AM, bharath reddy >> wrote: >> > Hi Matt, >> > >> > Thanks for replying back, here are the details : >> > >> > Distro : >> > root@devrt:~# cat /etc/os-release >> > NAME="Ubuntu" >> > VERSION="12.04.3 LTS, Precise Pangolin" >> > ID=ubuntu >> > ID_LIKE=debian >> > PRETTY_NAME="Ubuntu precise (12.04.3 LTS)" >> > VERSION_ID="12.04" >> > >> > cd /var/log >> > ls -lrt (I'm showing only latest) >> > -rw-r- 1 syslogadm 124 Oct 8 09:58 kern.log >> > -rw-r- 1 root adm 529 Oct 8 09:58 apport.log >> > -rw-r- 1 syslogadm 3086 Oct 8 10:00 syslog >> > -rw-r- 1 syslogadm 113879 Oct 8 10:00 auth.log >> > >> > root@devrt:/var/log# cat kern.log >> > Oct 8 09:58:10 devrt kernel: [3001033.121438] /usr/sbin/apach[5529]: >> > segfault at b54d9f80 ip b54d9f80 sp bfc702dc error 14 >> > >> > root@devrt:/var/log# cat apport.log >> > ERROR: apport (pid 5532) Thu Oct 8 09:58:11 2015: called for pid 5529, >> > signal 11 >> > ERROR: apport (pid 5532) Thu Oct 8 09:58:11 2015: executable: >> > /usr/lib/apache2/mpm-prefork/apache2 (command line "/usr/sbin/apache2 -k >> > start") >> > ERROR: apport (pid 5532) Thu Oct 8 09:58:11 2015: >> is_closing_session(): no >> > DBUS_SESSION_BUS_ADDRESS in environment >> > ERROR: apport (pid 5532) Thu Oct 8 09:58:11 2015: apport: report >> > /var/crash/_usr_lib_apache2_mpm-prefork_apache2.0.crash already exists >> and >> > unseen, doing nothing to avoid disk usage DoS >> > >> > root@devrt:/var/log# cat syslog >> > Oct 8 09:58:10 devrt kernel: [3001033.121438] /usr/sbin/apach[5529]: >> > segfault at b54d9f80 ip b54d9f80 sp bfc702dc error 14 >> > Oct 8 10:00:01 devrt CRON[5582]: (smmsp) CMD (test -x >> /etc/init.d/sendmail >> > && /usr/share/sendmail/sendmail cron-msp) >> >> Apache is segfaulting.

Re: [rt-users] Regarding Apache server failure
Matt, I don't think it is a problem with RAM or any hardware, because when I revert my changes in RT_SiteConfig.pm (with out LDAPAuthentication) apache starts with out any error. Thanks, Bharath.
