I have the same problem since last week. I have tried to use several different workflows but it keeps disconnect all the time.

Ok, so we need to find the commit that don't have this problem and do a checkout...

check task manager / system resource usage. That type of sudden hard crash usually indicates you ran of out system RAM

Sep 17 '24 06:09 mcmonkey4eva

I have the same problem just now nope, system RAM is only 43%

EDIT: added video with hardware monitoring https://github.com/user-attachments/assets/a132b7f0-14de-450e-a929-f3101704a5a9

Sep 17 '24 10:09 bramvera

I have the same problem on flux dev and schnel on both fp8 and 16 I checked the task manager for running out of resources but its not the issue. I also used workflow examples. my setup i7 10700K- RTX 3060 12GB, 32 GB 3600 MHz, Win 10 . I guess I can use the dev on fp16. cant I? somebody has a solution? i'll be greatfull

ok found a solution, at least for me fixed this issue:

Run: sysdm.cpl
Windows System Properties box, ensure that you are on the Advanced tab.
Click the Settings button from under the Performance section.
On the Performance Options box, go to the Advanced tab.
Click the Change button from under the Virtual memory section.
Click Change, uncheck Automatically manage paging file size for all drive:
on your system drive, for is C: change to No paging file, click Set, reboot

after rebooted set back again to System managed size, click Set, reboot one more time

I'm no longer have the ComfyUI sudden crash issue

Try uninstalling pytorch and changing its version. There have been reports of such issues occurring due to pytorch.

Sep 17 '24 13:09 ltdrdata

@ltdrdata I just wanted to say that changing the pytorch version to 2.10.0 causes the "C:\ComfyUI_windows_portable>pause Press any key to continue . . ." to happen on startup immediately after the "Checkpoint files will always be loaded safely." text.
