I suggest you to use the latest slapd version and mdb instead of bdb/hdb which is deprecated.

I have two node MMR ldap cluster with hdb, but for some reason one of the servers CPU get spiked every minute, I am not sure what is causing this spike every minute, we have same server configuration in both the server. Also when i do db_stat on *.bdb files this server is taking too long to respond for db_stat, i am pasting top and strace out put of that thread here. Also attach a graph shows cpu spikes and active threads spikes in both the servers (green and yellow lines),
