Hello and thanks for the quick response.
I am posting some more relevant information in case that will help
diagnose the situation better.
Hardware information & Versions used.
a) openldap-2.1.30
b) Berkeley DB 4.2.52
c) Hardware: CPU - Intel p4 1.4 GHz, 1 GB RAM, 250 GB IDE Hard Drive
We have around 5000 registered users of which 350 check email daily.
However being popular domains, we get a lot of spam as well as bounced
invalid mail (where someone is using our domain as return mail). So after
putting some filters/firewall in place we can determine that we get
around 3/4 requests a second.
You have suggested using db_recover which we have tried. As per what we
understood, db_recover can be used when our database is corrupt and we
need to recover
data but in our case ldap goes off not the data. In log file it shows
authdaemon.ldap TEMP fail. I am pasting below the contents of our
slapd.conf file if that will further assist in debugging the issue we are
facing. If you could tell me what other information is required, I'll be
glad to fish it out for you.
