With James' last patch for this problem, I haven't had any zombies in the GCC testsuite for a couple of months. My c3k running 2.6.20 hasn't crashed in the same period. Before, it was crashing every couple of days. I'd encourage James to queue this patch for the next merge even if it isn't perfect. I tried the testcase from the alpha PR and it didn't cause a problem. I am seeing timeouts in some thread intensive tests. For some reason, these are significantly more frequent on pa8800 with a 64-bit kernel. I haven't had a chance to investigate but we may have a deadlock somewhere. I did have a software lockup using a UP kernel a couple of weeks ago. Dave -- J. David Anglin [email protected] National Research Council of Canada (613) 990-0752 (FAX: 952-6602)
