Description ivan 2010-04-12 03:42:34 UTC

A recent (Apr 6-7?) build of NB constantly runs the 
"Active Reference Queue Daemon" consuming all of a whole CPU's
cycles. My machine would've been unusable if it didn't have two CPU's.
I'll attach a few sample stack traces ...

This doesn't always happen.
From Apr 6-7 I hadn't seen this til today.
The main thing that changed today was that I opened the cnd.kit
project (in my attempts to experiment regarding the thread
"FileUtil-Refresh-All is killing me".)
I exited and restarted NB but still had ARQ hog the cpu.
I worked for a while with this and then closed cnd.kit.
The hogging went away.
I re-opened cnd.kit but the hogging didn't come back.
So, nothing very conclusive unfortunately ...
