<PRE>Hello,

 
I am having an issue with services segfaulting on my server.  I can't really
gleen anything from the logs that would point to something that is being
done specifically at the time this happens.  There is nothing in the logs
except the normal kind of things going on right up until the services dies.
My IRCops tell me that it has happened to them on more than one occasion
when manipulating the xOP lists on various channels.

 
Excerpt from the logs

 
[Nov 08 18:58:02 2007] PANIC! signal 11 (no buffer)

[Nov 08 18:58:02 2007] Services terminating: Segmentation fault
