Comment 2 Karsten Keil 2006-02-20 13:10:13 UTC

Hmm seems that the treadlist of process 4175 is corrupted.
Can you reproduce this and save a ps ax before you shutdown, to see which process was corrupted.

Comment 3 Stephan Binner 2006-02-20 13:31:43 UTC

I cannot reproduce it. Will try to remember saving process list for future reboots.

Comment 4 Karsten Keil 2006-02-20 15:27:07 UTC

OK, I searched also mainline lists and reports, did not found any matches yet.
Please come back (or close it after some time) if it happens again.

Comment 5 Olaf Kirch 2006-02-22 11:22:54 UTC

I'm closing this for now. Please reopen if it happens again.

Comment 6 Karsten Keil 2006-02-22 13:33:27 UTC

Hmm, we already got similar reports (e.g. from IBM for ppc
152560 - LTC21869). I did not mark it as dup because of the differnt arch,
but maybe it is really a duplicate case and this suggest, that here is
some problem in task managment.
