[horde] Getting apache to dump core

[Kevin Konowalec]

Not really a horde-specific problem but I'm hoping someone here would  
have an idea...

So we've recently upgraded from OpenBSD 3.8 to OpenBSD 4.1 on our  
horde cluster.  Everything seems fine and dandy so far except that  
now all of a sudden I'm seeing the following messages in my apache  
error log:

May 28 13:07:27 src at dwc1 httpd[19972]: [info] server seems busy, (you  
may need to increase StartServers, or Min/MaxSpareServers), spawning  
16 children, there are 26 idle, and 51 total children
May 28 13:07:57 src at dwc1 httpd[8848]: [info] [client xxx.xxx.xxx.xxx]  
(32)Broken pipe: client stopped connection before send mmap completed
May 28 13:08:07 src at dwc1 httpd[19972]: [notice] child pid 25356 exit  
signal Segmentation fault (11)

I'm most concerned about the segmentation faults (which I wasn't  
seeing on the old server running 3.8 with older versions of horde/ 
imp).  The problem is I can't get the child processes to dump core to  
find out why they're segfaulting.  Can anyone suggest a way to make  
it happen?

Thanks!
