Can anyone help with this ?
I'm running openldap 2.1.16 with a bdb db-4.1.25 backend. I have a sendmail server that queries ldap for its aliases.
During times of high mail volume, ldap core dumps. Over a period of a couple of minutes i can watch slapd consume all system memory and then crash. I can simulate this quite easily with a looping perl script sending a couple of thousand messages.
I have configured the following indexes in an attempt to improve the performance.
index objectClass eq
index cn pres,eq
index uid pres,eq
index sendmailMTAAliasGrouping pres,eq
index sendmailMTAHost pres,eq
index sendmailMTAKey pres,eq
index sendmailMTAAliasValue pres,eq
The ldap box is running FreeBSD 4.7 with a PII 350 and 512mb of ram.
The sendmail server is a p4 2.4.
Is it possible that the sendmail server is too grunty in comparison to the ldap server ?
