  34 <PRE>&gt;&gt;<i>      This is bizarre, and looks like memory corruption; can you
  35 </I>&gt;&gt;<i> reproduce
  36 </I>&gt;&gt;<i> it consistently?
  37 </I>&gt;<i>
  38 </I>&gt;<i>Not really. As I said, I suppose the machine on which the services are
  39 </I>&gt;<i>running (which also is our main hub server) was probably under attack -
  40 </I>&gt;<i>just like yesterday, *sigh*.
  41 </I>&gt;<i>The whole network froze and other servers (including mine) splitted, and
  42 </I>&gt;<i>when we came back there was no sign of services, just that core file. I
  43 </I>&gt;<i>didn't find anything strange in the logs either.
  44 </I>&gt;<i>I didn't check the cpu load when I logged onto the machine, but I've
  45 </I>&gt;<i>heard of some attacks that manage to rise the load to  100%. Could that
  46 </I>&gt;<i>be the case?
  47 </I>
  48      Such attacks are possible, but I doubt those are related to the crash.
  49 It's more likely the flood triggered a bug somewhere in Services that
  50 corrupted memory--I've heard reports of such but have never managed to
  51 track it down.  Version 5.0 should be more stable in that regard, I hope.
