I'm noticing hang issues again with 0.91.2 on Solaris 10 x86. It doesn't
appear to be associated with a particularly malformed message because
when it starts hanging, if I restart it, things resume normally for a
while. The incoming queue clears out.
Just recently I happened to be checking the incoming queue and noticed this:

I tried the gdb bt bit, but doesn't show the stack trace that I'm used
to seeing:

And a bunch more of that. I know when clam is compiled gcc is supplied
the -g, so not sure why all the "??".
This gdb session was done in the global zone. Not sure if it'll work in
the zone where clamd is actually running, but I'll try that next time.
