EBS 12.2.6 login Page is taking long time to load

EBS Login Performance Issues:

After providing username and password in the login page of EBS 12.2.6, loading home page is taking very long time to load.

weblogic console url shows that one of the oacore servers, oacore_server2 is in WARNING state due to Max number of Stuck Threads reached.
