Hi,
I'm having some problems with fedora-ds and postfix in a high-rate
environment. First, let me say that we are migrating from openldap-1.2.2 to
Fedora-DS. The configuration with postfix+openldap has to be migrated to
fedora-ds and the postfix+openldap works great in the high-rate
environment. I have a relay_recipient_maps and a alias list which both use
ldap. However, ldaps connections (and ldap) connections to fedora-DS
seem to time out in a high-rate environment. In slow-rate environment were
there are a few 10s of emails an hour, things work fine. In the high-rate
where you receive 1-5 of emails per second, I am seeing lots of temporary
lookup failures. My configuration looks exactly like the POSTFIX Wiki
configuration on the
directory.fedoraproject.org/wiki page.
We did some debugging to take a look at postfix, which attempts to open a
connection to the ldap server and does, then it wants to perform multiple
lookups per connection but this doesn't work--it seems for some reason that
postfix is unable to do more than one lookup per connection. The
fedora-DS ends up with many connections from postfix which eventually
time-out.
Any ideas as to what could be wrong?
Thanks,
Jeff
