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.
49It's more likely the flood triggered a bug somewhere in Services that
50corrupted memory--I've heard reports of such but have never managed to
51track it down. Version 5.0 should be more stable in that regard, I hope.
