I am getting blue screen on DPM 2010 with a newly built Windows Server 2008 R2, following is the mini dump. Any idea what is causing this ? No memory dump was created. Use !analyze -v to get detailed debugging information. BugCheck 1, {74cd2dd9, 0, ffff, fffff88005478c60} Probably caused by : ntkrnlmp.exe ( nt!KiSystemServiceExit+245 ) Followup: MachineOwner --------- 1: kd> !analyze -v ******************************************************************************* * * * Bugcheck Analysis * * * ******************************************************************************* APC_INDEX_MISMATCH (1) This is a kernel internal error. The most common reason to see this bugcheck is when a filesystem or a driver has a mismatched number of calls to disable and re-enable APCs. The key data item is the Thread->KernelApcDisable field. A negative value indicates that a driver has disabled APC calls without re-enabling them. A positive value indicates that the reverse is true. This check is made on exit from a system call. Arguments: Arg1: 0000000074cd2dd9, address of system function (system call) Arg2: 0000000000000000, Thread->ApcStateIndex << 8 | Previous ApcStateIndex Arg3: 000000000000ffff, Thread->KernelApcDisable Arg4: fffff88005478c60, Previous KernelApcDisable Debugging Details: ------------------ FAULTING_IP: +74cd2dd9 00000000`74cd2dd9 c3 ret CUSTOMER_CRASH_COUNT: 1 DEFAULT_BUCKET_ID: DRIVER_FAULT_SERVER_MINIDUMP BUGCHECK_STR: 0x1 PROCESS_NAME: mms.exe CURRENT_IRQL: 0 LAST_CONTROL_TRANSFER: from fffff80001cb8b69 to fffff80001cb9600 STACK_TEXT: fffff880`05478a28 fffff800`01cb8b69 : 00000000`00000001 00000000`74cd2dd9 00000000`00000000 00000000`0000ffff : nt!KeBugCheckEx fffff880`05478a30 fffff800`01cb8aa0 : fffff880`05478c60 fffffa80`06f96fc0 00000000`00000000 fffff880`05478b00 : nt!KiBugCheckDispatch+0x69 fffff880`05478b70 00000000`74cd2dd9 : 00000000`00000000 00000000`00000000 00000000`00000000 00000000`00000000 : nt!KiSystemServiceExit+0x245 00000000`02f9f0f8 00000000`00000000 : 00000000`00000000 00000000`00000000 00000000`00000000 00000000`00000000 : 0x74cd2dd9 STACK_COMMAND: kb FOLLOWUP_IP: nt!KiSystemServiceExit+245 fffff800`01cb8aa0 4883ec50 sub rsp,50h SYMBOL_STACK_INDEX: 2 SYMBOL_NAME: nt!KiSystemServiceExit+245 FOLLOWUP_NAME: MachineOwner MODULE_NAME: nt IMAGE_NAME: ntkrnlmp.exe DEBUG_FLR_IMAGE_TIMESTAMP: 4b88cfeb FAILURE_BUCKET_ID: X64_0x1_nt!KiSystemServiceExit+245 BUCKET_ID: X64_0x1_nt!KiSystemServiceExit+245 Followup: MachineOwner ---------
