I keep occasionally seeing
Aug 20 13:10:10 balancer /kernel: pid 38444 (pound), uid 0: exited on signal 6
(core dumped)
in /var/log/messages
and although I have set LogLevel 2 in pound.conf, no other
relevant info.

I guess this is worker crashing because pound keeps working.
I suspect that this could be one of the reasons for the intermittent
request failures that I also experience. Any suggestions on debugging
or fixing this ?

I'm running Pound-current as of June 15, 2004 under FreeBSD 4.10.

Tried to install 1.7-stable, no result, still keeps crashing:
Aug 20 16:20:14 balancer /kernel: pid 72426 (pound), uid 0: exited on signal 6
(core dumped)
Aug 20 16:20:14 balancer pound: MONITOR: worker exited on signal 6,
restarting...

Here is the core stack dump:

#14 0x0 in ?? ()

I guess the problem is/was dynamic linking with the wrong ssl library,
dump of binary pound contained libcrypto.so.3 which was the old
(and presumably single-threaded) one. Statically linked with the
freshly built thread-safe libcrypto.a instead, hopefully this fixes
the problem.

Good catch Dmitry. Let us know how it works.

BTW - please avoid 1.7, as it had known problems. Try -current instead.[...]

openssl-base on 4.x is not threaded. Use openssl from ports to have a
threaded version.

If you're using FreeBSD 4.10, I don't believe there is a port for
Pound-Current, just Pound-1.7. Note that there are several patches applied
to Pound-1.7 in the ports collection specific for FreeBSD. If you just get
the latest Pound-current, the patches from 1.7 in the port won't apply
correctly.

I do have a FreeBSD port I created for Pound-Current (081904) that applies
the FreeBSD specific patches for that version if you want it, email me
off-list.

Not sure this is the problem you are running into, but it may be.

Regards,

Jay West
