Description

Just got this when (I _think_) the box was removing a larger tree in /usr/obj.

core.txt is here:

http://87.78.98.243/tmp/core.txt.21

Full dump is in ~swildner/crash/crash21.txz on leaf.

Regards,
Sascha

I should add that this is a i386 box.

#2 Updated by vsrinivas almost 2 years ago

softdep was failing to take its lock when entering process_workitem via
request_cleanup from newdirrem.

Could you please try the attached patch?

  • Status changed from New to Closed

Closing this for now, since with Venkatesh's fix (9d106dfa699e433e63b3876290375371060b91f9) the panic no longer occurs under these conditions.
