I don't think the results are much ( they are below). We are running ClamAV
installed from a package. WIll I need to recompile clamd myself to use
gdb?

I don't know what you mean by "alighnment issue".
alignment issue, for example: on Sparc memory reads of 4-byte in size
must be 4-byte aligned. If it is not properly aligned you get SIGBUS.
This issue doesn't exist on x86, at least not for regular instructions.
dmesg output is going into my logs already, and I can see no indication
of an event around the time the clamd daemon abends. It is now
happening as often as every 2 minutes.
I have a core file, but my adb(mdb) is rusty.
Please install gdb, and then run these commands, and paste the results:
$ gdb -c core /usr/sbin/clamd
...
(gdb) thread apply all bt
where 'core' is the name of your corefile
/usr/sbin/clamd is the full path to clamd
(gdb) is the gdb prompt
'thread apply all bt' is the command you type in
It should be possible to get a stacktrace with mdb too, but I'm not
familiar with it.
