Hi everybody,
I've been running a Trac install for about a month on multiple
repositories just using tracd and it's been working fine. Then, a few
days ago, it crashed. I restarted, and worked for a while. Then
crashed again, and then again, etc. Now it seems to serve up a couple
pages then crash. And it's never totally consistent, sometimes it'll
crash on a wiki page, sometimes not...the only consistent part is I
haven't been able to see the svn revision log page on any project
since this started.
So I've tried a bunch of things, to no avail. Simplifying it down to 1
project and the error still occurs. The logs in the project folders (I
turned logging on at the highest level) don't seem to show anything.
When I run it not as a daemon, it says it has had a segmentation
fault, but nothing more.
I've now run it under gdb:
$ gdb $(which python)
(gdb) run /opt/trac-0.10/scripts/tracd -p 8080 /srv/trac/yourproject
It still fails, and outputs this little bit:
Program received signal SIGSEGV, Segmentation fault.

My specs are:
- Centos 4.x
- Trac 0.10.3
- Python 2.3.4
- SVN 1.2.1
- swig 1.3.24
Not sure what else is needed...any advice would be amazing, I've been
tearing my hair out over this, as it seems so strange that it was
working one day and not another.
And I have tried running it as a CGI, and get similar
situations..though it seems harder to debug, as I don't get anything
useful in the web browser (only "misconfiguration..blah blah"), and my
apache error log also doesn't seem to show much of anything either.
Thanks in advance!
Cameron
