Segmentation Fault - RT3.8.4 - Apache2

RT Users

Hi,

ubuntu 9.04 dual Xeon process, 2GB memory.
New install RT 3.8.4 with imported RT 3.2.2 database and followed the
README.txt and Upgrading.mysql docs.

For what ever reasons, when RT has been idled for a period of some hours,
more like 10 hours, when people are not accessing via website, than when I
logs in and hit http://helpdesk.mydomain.com I get
a blank white page and sometimes the default generic RT page. However,
when I refresh it a couple time, the regular webpage loads correctly and
checking at /etc/apache2/error.log indicates
the following:

[Thu Aug 06 07:21:43 2009] [notice] child pid 2784 exit signal
Segmentation fault (11)
[Thu Aug 06 07:21:43 2009] [notice] child pid 2785 exit signal

Segmentation fault (11)

Segmentation fault (11)
[Thu Aug 06 07:22:21 2009] [notice] child pid 2786 exit signal
Segmentation fault (11)
[Thu Aug 06 07:22:24 2009] [notice] child pid 3341 exit signal
Segmentation fault (11)
[Thu Aug 06 07:22:24 2009] [notice] child pid 3342 exit signal
Segmentation fault (11)

It appears to me that RT needs a constant connection or something to keep
it alive. When someone is logged into the website and have the site
refresh every 2 minutes segmentation fault does not occurs.

I have research and played with different settings on httpd.conf, removed
ufw (ubuntu firewall), removed PHP5, removed apparmor (ubuntu selinux)
and no resolution. RT 3.8.4 is the only website this box is hosting and it
has a single static IP and DNS setup correctly.

Does anyone know what could be causing this? or seen this occurance ?
ideas? Any suggestions would be appreciated!

This has been known to occur with some versions of DBD:mysql. I believe
the latest versions fix this; I’m currently using 3.0008.

Hi Curtisb,

I’ll give that a shot and see what happens. I’ll up it to the latest and
see what happens
