Customer has 6 instances of the policy store, all in multi-master replication. When all of these stores are online, an old, outdated login page is intermittently served for one of our applications. This problem does not occur when two particular instances are taken offline.
This was due to a replication failure since the data on the two bad instances was not in sync with the other four.
Release : 12.5
Component : SITEMINDER POLICY SERVER
Fix the replication issue or otherwise get the data in sync between the policy store instances.
