I have two OpenLDAP 2.4.11 servers, using BDB 4.6.21 (Patches 220.127.116.11 & 18.104.22.168
& 22.214.171.124 applied), hosted on CentOS 5.2, setup for multi-master replication. Works
great except that every couple of months either one of the slapd servers will pin the CPU
at 100%. Requests continue to be served without any noticeable degradation in response,
and no discernable errors in the LDAP logs.
I see the forums frequently mention CPU utilization issues, but most of the time this
seems to be related to non-indexed queries, which I don't believe is the cause in this
Restarting slapd resolves the issue, temporarily ...
Any suggestions would be appreciated.
