In the last week I have had multiple crashes. Here are the facts: - Running latest MacOS Tahoe on M4 Macbook Air - Running Win 11 ARM under latest Parallels with latest Parallels Tools - System crash usually preceded by scrolling in Excel, but not always - Twice, Parallels application memory use exploded from 8GB to 123GB The last point is mysterious as in both cases it happened during idle time, even with only one light Excel file open. For reference, I have animations and "glass" features off in Windows, and have Excel UI "optimized for compatibility". The problem happens regardless of whether Parallels display settings are on "best for Retina" to "best for External".
I'd be interested in feedback on this as I am also starting to suspect that Excel is the culprit or a major contributor to this problem of Windows suddenly crashing. This is also being discussed here: https://forum.parallels.com/threads/sudden-shut-down-of-windows-11.369850/#post-946206 and https://forum.parallels.com/threads/windows-11-keeps-crashing-randomly-on-multiple-machines.369312/ Thanks.
Curious what version of Parallels you are running. I had similar issue. I work with very large Excel workbooks, local database, Visio and other O365 apps. They had me to back to a different version and it has been Happy Days ever since. https://forum.parallels.com/threads/vm-running-mac-memory-out-to-100gb.369767/
Using EXCEL and scrolling up and down often I get a big Crash of the whole win11 system!!! I made a macro reproducing the problem: after scroll up down and right and after a certain number of select (and repaint) the system crashes: systematically.
Thank you, that's very interesting. I'm here because I'm getting a lot of sudden crashes of Parallels, mostly it seems when using Excel. However before that I was getting the issue with resources running out on the Mac side that you described. (That hasn't happened lately). I wonder if the two issues were linked?
This has been happening to me as well on both my work and personal computers. Happens almost every time I use excel in the same manner described above. Honestly if it isn't fixed soon I'll have to get a pc and forego trying to use parallels it's becoming too much of a hinderance to do any real excel work.
May not be the same issue I was experiencing. But might be worth a try to fall back to 26.2.2 version in my other post. I had to do an uninstall, then install the downlevel version. I am on 16in MBP M5 Max with 48GB memory. I upped my VM from 4 vCPU to 6 vCPU, 16GB memory to 24GB memory. I beat the heck out of the Win 11 VM daily. Multiple Excel workbooks open right now. One of them is 185k rows and 29 columns. Filtering, pivots, and xlookups. (4) Other Excel workbooks, one is only 36k rows, but loads of pivots and tables calculating stuff from the Pivots. Also have Access open with linked tables, and the local table that created that giant workbook. (6) PowerPoints. Of course Outlook, OneNote, CoPilot...No Visio opened right now. Just wanted you to understand my workload. If you fall back and still have issues I would open a case. For me throughout the day the VM memory usage would grow and grow. On days where I would hit 240-250GB memory usage, it would crash. Guessing some sort of a barrier at 256GB. I was rebooting every morning to help avoid it, which was an inconvenience. I knew it had to be a bug as I had a 14in MBP I took back after a week, that had the same issue. They had me build a fresh VM using the MS Download. Took me about a week to fully cut over to the new VM. They also provided detailed instructions for collecting all the data they needed. Was easy to do and upload.
