Hi,

Ldap daemon was being restarted every so many minutes. All the consumers were out of sync and had to be re-synced. This specific master in question in MMR setup was restored from other master and the issue went away. running 2.4.37 on centos6 with hdb backend on the masters and lmdb on the consumers.

Searching thru the list shows a lot of hits with "too old", AFAIK ntp is kept quite closely. serverid "000" no longer exists as it was decomissioned since last year, hence contextcsn is really old. Not sure if that played a role in this havoc or not. Could you tell me what "srs" and "log" means in the context below?

Following is what I found in the log, and there were a lot of these which probably contributed to restart of the daemon:
