  34 <PRE>Hello,
  35
  36
  37
  38 I am having an issue with services segfaulting on my server.  I can't really
  39 gleen anything from the logs that would point to something that is being
  40 done specifically at the time this happens.  There is nothing in the logs
  41 except the normal kind of things going on right up until the services dies.
  42 My IRCops tell me that it has happened to them on more than one occasion
  43 when manipulating the xOP lists on various channels.
