Default BES5 HA: Spreading agent load

First Post!

Our environment consists of an HA BES5 Setup, with about 780 users across 15 exchange servers. (In addition to another non-HA server on the other coast due to latency) When there's an issue and a failover or a service restart is required, it takes hours to scan through some of our users 20gb mailboxes (reload_fldrs is the killer). In addition, sometimes it would be beneficial to just kill an agent process responsible for an individual exchange instead of killing an agent with 500 users on it.

Anyway, I did the following: (playing around with the standby instance).

Changed NumAgents and NumAgentsFullServer to 15 (Decimal) under Agent key.
Added MaxUsersPerAgent, and set it to 100 (Decimal) under Dispatcher key.

Restarting the dispatcher detects the 15 agents value, and according to the processmon, dispatcher also picks up the 100 users valua on startup, but the user/agent breakdown doesn't change. (Is it because it's a standby instance?)

Any suggestions?

If it is a standby instance it doesn't have any users loaded ... so I'm confused at your question.

Both active and passive servers should have the registry settings in place and when the failover occurs users should be properly allocated.

32-bit, registry keys in proper locations.

I'm going to try taking both servers down tonight...
