Hi folks –

 

I have an issue with oldap 2.36 in which every ten minutes, slapd starts consuming all available CPU resources briefly.  When this happens ldap searches timeout. 

 

I have bumped up the cache size to 1.5 GB  dn2id.bdb and id2entry.bdb are approx. 60 mb combined. 

 

I’m reading through this:

 

https://www.openldap.org/devel/admin/tuning.html

 

I get errors (mismatched version) when I run DB_STAT  (database environment version mismatch)

So, I don’t have much more to report there. 

 

I set logging back to the default to minimize logging.

 

There are three nodes in our cluster – one master. 

 

Is there anything else I can look at to help troubleshoot? I am wondering what would cause slapd to peg the cpu at exactly 10 minute intervals.

 

Thanks for any help.
