Windows bugcheck code 244

If event 41 is logged because power to the computer was interrupted, consider obtaining an uninterruptible power supply UPS such as a battery backup power supply.

An underpowered or failing power supply may cause this behavior. For example, if you added RAM or additional devices or hard disks when this problem began, the power supply may cause the problem. To further isolate this problem, kindly go through this guided walk-through troubleshooting to help identify what really is causing it.

Here's the link. Was this reply helpful? Yes No. Sorry this didn't help. Thanks for your feedback. This thread is locked. The bugcheck was: 0xb 0xc, 0xfffffdb5aa7a, 0xfffffa88a5db69f0, 0x Shame I accidentally had dumps turned off, but I was able to reproduce this one a couple of times last night when downloading a dozen large torrents qbittorrent - probably about GB total while maxing out the drive speed.

I'll see if I can get some minidumps later today. If it helps at all, here is all that was produced in the dumps folder.

Would seem that the initial crash dump failed to get created? Unless some peak occurs or something I don't know about. I also just ran into this bug twice today. Is there anything I do to help with this? Running latest version of ZFS for windows. Probably you should send it over PM to developer in case it has personal data.

I did a quick analysis and found that it was due to a cccopywriteex call. I tried to disable the cache and I haven't had a bluescreen until I tried to export. Been copying an 8gig file to trigger it here, but I seem unable to.

Thanks, I'll give it a try next time I blue screen - currently it has been pretty stable! Thanks lundman unfortunately no luck with this one. I tried to install it over the top which caused an immediate bluescreen near completion.

I tried a few more things. I'm not sure if there's conflicts with something else that I'm running as I'm not sure they were all caused by ZFSin but it was the only thing that I was playing around with.

I have been running this on my PC so unfortunately haven't been able to retain the full dumpfile as the crashes were in rapid succession.

Is it worth sending you the mini dumps for analysis? This topic is for programmers. If you are a customer whose system has displayed a blue screen with a bug check code, see Troubleshoot blue screen errors.
