We're still experiencing this issue. I've observed a couple of things
during the latest event.
I mentioned before that netstat -a shows many smb processes in CLOSE_WAIT
state when this problem occurs. I happened to strace on a process that was
stuck in "recvfrom(1315,". When I killed this process many of the hung smb
processes terminated and the Samba service was responding again.
I've noticed the following error in the messages file:
Dec 13 18:16:20 valhalla smbd[18005]: [2004/12/13 18:16:20, 0]
tdb/tdbutil.c:tdb_log(725)
Dec 13 18:16:20 valhalla smbd[18005]: tdb(/var/cache/samba/locking.tdb):
tdb_lock failed on list 99 ltype
=0 (Resource deadlock avoided)
This particular error showed up prior to samba being restarted. When the
service is restarted many of these show up in the log. I also notice that
many times during an event the messages file contains the following
errors:
Dec 13 19:29:33 valhalla smbd[28820]: domain_client_validate: Domain
password server not available.
Dec 13 19:29:33 valhalla smbd[28820]: [2004/12/13 19:29:33, 0]
auth/auth_domain.c:domain_client_validate(17
0)
Not sure if this is a coincidence.
