Backup Exec 10d hangs my exchange cluster

Here is the scenario.
1.  I have  two server 2000 servers clustered.
2.  I am running exchange 2003 on the cluster.
3.  The cluster is connected to my SAN.
4.  Backup exec 10d with exchange remote agent running

Every morning around 4am, my exchange server hangs.  When I come in, in the morning I have to move the cluster over to the non-active node for users email to start working again.

I did see resarch and it only happens when I install the backup exec remote agent on the exchange clusters.  If I remove them, then the problems goes away.  But I need the agent to backup the individual exchagne mailboxes.

How can I stop this from happening?
Is there a schedule time in Exchange 2003 that it does some type of database optimizing that is conflicting?
