Subject mod_perl 1.30 seg faults
Date Fri, 29 Oct 2010 19:50:10 GMT
I'm running a modperl installation with 1.30 and apache 1.3.42.

I recently upgrade from Ubuntu 9.04 to Ubuntu 10.04 and now every time a mod perl process
shuts, it dumps core.   None of the application code changed.   Maybe modperl isn't playing
nicely with perl 5.10.1 (the old machine had 5.10.0)?  Luckily it's not causing a problem
since the core dump doesn't happen during a regular request.  However it was fun watching
the machine try to write 20gb of core dumps every few minutes....

Does anyone have any idea why this is happening or what I can do?   I know 1.30 is old and
apache 1.3.42 is end of life.    Yes we will be upgrading to a newer version in the future,
but I'm trying to find an interim solution over the next few months.

Any help is much appreciated.
