Ah, it's happening to you as well? Happened here twice or three times
already:(

Yeah, same here.
freebsd? amd64? what version of Freebsd?
I posted to clamav list, and they gave me a POSSIBLE 'fat finger' that
might be causing it.
I am going to try this below and see if it helps.
clamav also asked, that once it hangs, can we use this to generate a
core file:
If you still have one of those hung 0.97.1 (or come across in the future) can
you run
$ gcore<pid>
This should generate a core file of the hung process that can be investigated
later
(as long as you still have the coresponding clamd and libclamav binaries too).
Best regards,

yes, but darn clients start whining when they can't get their facebook invites
immediately :-)
trying to reproduce in lab with daily and safebrowsing files, also, trying
with the emails that made it hang.
left some backup systems still running 0.97.1 in the field.. if a backup
system fails, we can leave it hung till we figure out what happened.
so, WHAT that might affect threading did you change from 0.97 to 0.97.1?
also, this affected boxes running TCP socket, as well as running unix sock.
and, only on amd64 boxes.. all the i386/32bix boxes are fine.
Maybe this one:
http://git.clamav.net/gitweb?p=clamav-devel.git;a=commitdiff;h=bbfe830c935837cfc357541cb307a7b863394abb;hp=d9ff9e65080d7c70de722e174d365d3b2cb312d3
But it survived a full regression test here (Linux/amd64).
Will go through the code again tomorrow and see if I can make it deadlock.
