Dear,
We've started observing strange & peculiar performance behavior for slapd
instances. While ldap bind response is more than 1.5 second on one server
then on another it's just 0.006 seconds.
Both the servers have similar OS, system resources & ldap version.
OS: RHEL 6.9
LDAP: 2.4.44
Backend: bdb
Could you please suggest some probable causes..?
Thanks & Kind Regards,
Saurabh Lahoti.

Could it be a slow local disk?

Dear,
After some rigorous checks & debug found the local FS was getting exhausted
due to huge amount of logs written by slapd daemon.
Unfortunately, this FS is system mounted locally (sda2) & hence couldn't be
expanded further. As a workaround, has restricted log quantity to 6000/10
seconds via rsyslog rate-limiting feature.
Ulrich,
Will check onto system for any slow local disk problem persists.. Many
thanks for your kind & valuable suggestion.
