DPM 2012 R2 Agent Not Reachable RRS feed

  • Question

  • Hi,

    We have a problem where the DPMRA service stops responding and the agent becomes unreachable. However, this problem only occurs on a Exchange Server running the mailbox server role.If i restart the server and agent becomes reachable however after a days it becomes unreachable.

    There is no problem with DNS, networking, firewall, DPM server or anything else. I enabled verbose logging on the DPMRA service and collected the logs, in which i found:

    "23E4    3684    10/30    12:36:59.497    05    defaultsubtask.cpp(74)            WARNING    CDefaultSubTask:: Thread holding the lock is 7996, TimerOrWaitFired:True, Abort on timeout: False, state: 0"

    23E4    1FC8    10/30    12:37:01.357    22    genericthreadpool.cpp(684)    [00000000009D0240]        NORMAL   CGenericThreadPool: Waiting for threads to exit

    Seems like a problem with thread limits within the OS itself? I wondered if anyone else has come across this problem in their environment and got a fix?

    PS: I have a case open with MS Support at the moment but its still stuck in 1st line and not getting anywhere.

    Thanks

    Mayur
