Hi,
We have a situation where LDAP query is resulting in a LDAP 80 level
errorduring a domain lookup. Yes I understand we need to fix this problem.
However, the side effect we see is the client's SMTP session hangs. Over a
period of time all SMTPD sessions are consumed and no mail is processed.The
only solution was to stop postfix and restart to free up the processes.
I was able to track it down to resolve_clnt.c for loop were it
continuouslykeeps trying until a non LDAP level error is returned. Even if the
client MTA connection has been closed, the smtpd process continues toretry
after 1 second sleep, thus, consuming LDAP resources. I suspect it continues
until the process time to live has exceeded but I didn't let itrun to see if
the smtpd process would die.
I have looked for a patch but I have not found one. Does one exist?
Any help is greatly appreciated,
Charles
