Re: AW: print throwing intermittent Segfaults

Hello,

I started to see the following when I setup a new server on CentOS 5.4 
and installed perl modules from CPAN on Dec. 4:

I do not see this on another server with CentOS 5.2 and perl modules 
primarily built Feb 09.

I think something has changed in either CentOS, Apache, or the perl 
modules I use in the interim.

I think it has something to do with Apache children being killed either 
because of size or request limit reached.

So, Denis, have you tried adjusting these:

The MaxRequetsPerChild especially seems awfully small.

Plus, you say you see the problem happening every 30 to 250 requests. 
(StartServers)8 * (MaxRequestsPerChild)15 = 120. This sounds like 
roughtly around the time you'd expect Apache children to die.

I had MaxRequests set at 2000 and saw the problem intermittently. I'm 
going to set MaxRequests to 0 to turn it off and see if it goes away.

I wonder if something has changed in Apache recently? Or, mod_perl?

Both servers are running Apache 2.2.3. One is running mod_perl 2.0.2 and 
the other one is 2.0.4. Judging on the version numbers...could this be a 
bug in 2.0.4?

Take care,
