Periodic hanging of logins across all IVS portals on an SA 4000 Cluster.
We have had a strange problem crop up ever since our upgrade from 6.2R4 to 6.4R2. Periodically (3 times now) we are seeing an issue where no one can login to their Juniper IVS portals. The landing page comes up but when you try and login it just hangs. We have 2 SA 4000 units in an active/passive cluster and when we fail the primary over to the secondary we are able to login again. The problem has also occurred on the secondary unit.
Not sure what is causing this issue, it seems to happen at random times but is becoming more frequent.
