Hello all,

I have installed a mail server with real users, stored in openldap.
The dovecot server sometimes hangs waiting for an answer from ldap, an
answer that doesn't come.  The openldap server does not crash, it just
sits there.  A restart of the slapd server makes everything work
again.

The system is a dual Xeon, fast raid disks and serves only ~70 users.
It is running debian-unstable, openldap 2.1 with ldbm backend.  All
default values from debian install, I didn't tweak cache nor threads
in slapd.conf.

When this happens, can you run a manual ldapsearch of the server (i.e., does slapd respond to your queries?). If not, it sounds like slapd is experiencing some type of lockup, which would be problematic. You shouldn't have to restart slapd to get it to be responsive again.
