Hi, I was not certain abt what info to put so I've given below all the info that I could gather. Kindly tell me if you require anything else.
openldap = symas-openldap-silver-2.4-12.1 bdb = bundled with symas ( 4.6 )
configuration in slapd.conf *cachesize 427275* *idlcachesize 427275* (there are approx 427275 entries in the db so i've that as the cachesize.) *threads 2* (this is a server which has web applications also running. so we have reduced openldap threads to 2.) *sizelimit 1000 checkpoint 10240 10 lastmod on idletimeout 120 timelimit 360 gentlehup on*
in DB_CONFIG, *set_cachesize 0 1985642496 1* (The total size of all .bdb files is 1813643264 bytes)
cat /proc/cpuinfo shows 7 cpus. It has 4gb ram and 8gb swap.
Thanks and Regards, Amol.

Yes, those are definitely issues that need addressing. Unfortunately, you don't really provide any useful information that would help with resolving it.
