  34 <PRE>&gt;<i>The problem they have is, that when such an attack starts,
  35 </I>&gt;<i>services after some time stop responding, making the ircd quit the link,
  36 </I>&gt;<i>and looking at the table of processes shows, that services sits there
  37 </I>&gt;<i>with 99% CPU usage, requiring kill -9 to be shut down.
  38 </I>
  39      Is there any way you can look into this with gdb and see where it's
  40 using all its CPU time?  I can try repeating the flood here but I suspect
  41 database size is at least a part of the problem.
