Workqueue lockup happens whenever memory usage is high

On a AGX Orin (32GB), whenever memory usage is high, I get:

Message from syslogd@orin at Jul 25 09:10:36 …
kernel:[60702.744863] BUG: workqueue lockup - pool cpus=5 node=0 flags=0x0 nice=0 stuck for 2699s!

I’m running Jetpack 5.1.1 and the application makes heavy use of NVDEC.

The device more or less locks up, and the only fix is to restart the device, which is not great.

It seems that other people have reported a similar issue and the “fix” was to not use so much memory. Kernel locked on Orin - #13 by c.m.harvey

It’s not OK for a device, especially a embedded system, to crash due to excessive memory usage!

I hope this will be fixed by Jetpack 6?

There is no update from you for a period, assuming this is not an issue any more.

Hi,
Please share the steps for replicating the issue on AGX Orin developer kit/Jetpack 5.1.1. We will set up and check.
