PAGE_FAULT_IN_NONPAGED_AREA (msiscsi.sys) – how to troubleshoot/resolve

bsodiscsistoperrorwindows-8.1

I am using Windows 8.1 Pro x64 with all updates installed. My machine is Lenovo W540 laptop and I have connection to iSCSI target (using gigabit wired Ethernet). iSCSI target is Synology NAS (DS415+). Quite frequently I'm getting BSODs and system takes dump and reboot. Error message is the following:

PAGE_FAULT_IN_NONPAGED_AREA (msiscsi.sys)

Screenshot:

I store VMware VMs on iSCSI disk and most often error occurs when I am taking snapshot or shutting down VM running from this disk, but I also noticed that sometimes error happens even when I am not running any of VMs stored on iSCSI disk, but again doing something with VMs stored on locally attached internal SSD.
My understanding is that to troubleshoot it properly I had to analyze dumps but I'm not sure how to do it or whether I will be able to get meaningful information out of those. Also maybe somebody already know what else can be done about this issue?

The obvious stuff to check is:

  • Antivirus software. Your AV software may be causing this problem.
  • Faulty hardware. Defective RAM or CPU can cause this to happen. (In this case, though I would usually expect to see many other blue screens with different bug checks.)
  • A driver bug. Since it seems to be a Microsoft Windows driver, this will require follow-up with Microsoft directly.

Other stuff you should try doing:

  • Check the disk for errors with chkdsk.
  • Repair any corrupted Windows files, e.g. with dism /online /cleanup-image /restorehealth.
