We are using 2 CA Directory Servers in our production as user store of Siteminder. We can see that one LDAP server is using 94% of the memory. The process which uses this memory is user-directory. We have 15G of RAM on the LDAP server. But not sure why its is using 94% of the memory. Is it due to the increased user logins? or Does it depend on the user count in LDAP server? How can this be fixed.?
