Re: AVN authz crashes

Sorry for the double-posting there-- didn't think my first message had gone through. Anywho, I got some help from #apache channel and managed to get backtraces for these segfaults. It actually looks like it's an issue with modauthkerb. I posted on the modauthkerb-help list here:
http://sourceforge.net/mailarchive/forum.php?thread_name=30504439.2581231894457538.JavaMail.root%40piers&forum_name=modauthkerb-help

One thing I find interesting is that from the backtraces, it seems modauthkerb is being called over and over for each file of a given checkout: it always fails at a different point in the checkout operation and I see a lot of init_creds and destroy_creds calls in those backtraces. If this is an intermittent problem with modauthkerb or libkerb it might be mitigated quite a bit if they were only called once per checkout/update operation...

Best regards,

Subject: AVN authz crashes

This one has me thoroughly confused:
SVN (via Apache) works perfectly right up until I add the following directive to my Apache configuration file: "AuthzSVNAccessFile /var/lib/svn/svn-authz.conf". Once that's there, I start getting random crashes on checkout and update.

The SVN client dumps out with the following error:
svn: REPORT request failed on '/svn/sentinel/!svn/vcc/default'
svn: REPORT of '/svn/sentinel/!svn/vcc/default': Could not read chunk size: connection was closed by server (http://sombrero.ridgetop-group.local)

In my Apache logs all I get is:
[Tue Jan 13 15:31:58 2009] [notice] child pid 2338 exit signal Segmentation fault (11)

My statistically insignificant tests just now put this error at occurring 5 out of 8 attempts when authz is enabled.

Does anyone have any idea what might be causing this or (more importantly) how to fix it?

Thanks,
Karl
