  • hi,

    I found that the CCR mailbox server need to take a hour to accept the mail from HUB's MAPIDelivery queue. We suspect that some of database encountered problem after failover. Checked that CCR is normal but the memory usage is high. Mailbox server is 8 GB ram and store.exe is using 5 ~ 6GB. Is it normal ?

    After a hour, the queue is back to normal. How can I found which database encounter problem ? The event log does not have any error recorded.

    Please help and thanks

  • The memory use by store.exe seems about right. It may even be a little low. :-)

    If you were restarting the information store service while it was in the process of replaying log files you'd see that sort of behavior. Your application log should have recorded an event when the database was ready to be used.

    Finding the source of a problem like this after the fact isn't always possible. Running PerfMon while the problem was ongoing would have provided you with lots of information that would be useful.

  • Hi,

    To narrow down the issue, as what Rich mentioned above, we can use the Performance Monitor tool to collect related information and then analyze it.

    Hope this helps.

  • 1. Would restarting Mail Submission Service Clears the queues and allow the mail for delivery ?

    2. Are Queues empty when a Failover/Failback is attempted ?

    As a last resource moving mailboxes to another store would help us fix the logical corruption that the Database is affected with!
