Signal 6 is SIGABRT -- see /usr/include/sys/signal.h.  A process dying
with this signal is usually due to it calling the abort(3) function.
That generally indicates that the process itself has found that some
essential pre-requisite for correct function is not available and
voluntarily killing itself, rather than the process being killed by
the kernel because it ran over resource limits or looked at memory
addresses funny or something.

Hmmm... there should be some sort of explanation logged by the clamav
processes as to why they've elected to abort.  You might find running
the daemon in foreground -- possibly under a debugger -- provides more
information.  See the 'Foreground' and 'Debug' items in
clamav.conf(5).
