Re: FC7 problem udevd: udev_event_run: fork of child failed: cannot allocate memory spewing over and over again on the console.

I finally tracked it down to some changes that were added to the sysctl to keep the OOM killer at bay.
 
The offending lines were:
vm.overcommit_memory=2
vm.overcommit_ratio=0

I am using the 2.6.22.5-76 kernel.  When I try and use the 2.6.22.1-41 kernel, I get the same result even though the 2.6.22.1-41 kernel has worked on those machines in the past.
 
I am using udev-113.12.  I get the same result if I roll back to udev-113.11.
 
Booting into single user mode also fails.  It gets stuck in the same spot.
 
Any ideas?
 
Thanks,
Bruce

Hmm, first report. Haven't seen anything like that from other users. Was
there a kernel update in the last days?
