SCCM client subcomponent vappcollector crashing several pc's
This week we have had several reports of pc's getting a BSOD upon login. PC's were receiving STOP 0x00000001 errors (APC_INDEX_MISMATCH (1)). After checking the minidumps they all show the vAppCollector as being the culprit. Disabling the SMS Agent Host Service stops the crashes. We are in the process of troubleshooting the issue but i wanted to see if anyone else out there has come across this. We recently upgraded to R3. Thanks in advance for any input. Our clients are all Win7 32 bit SP1 Heres one of the minidumps: Microsoft (R) Windows Debugger Version 6.12.0002.633 X86 Copyright (c) Microsoft Corporation. All rights reserved.

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.

To Follow up, we found the cause of the issue, it appears to be isolated. The dozen or so PC's all had corrupted App-V Clients. Boot into safe mode>disable sms agent host service>uninstall app-v client>restart sms agent host>reboot>re-deploy app-v client
