I don't know what I can do about this. Are you sure that "rwsem.h" was mentioned and not "rwsem.c" or some function whose name contains "rwsem"? We do have a patch to fix a problem with R/W semaphores that so far only crops up in conjunction with AIO as far as I know. Are you using AIO? I don't know of any way to get additional info, unfortunately the tech at the scene at the time didn't have a camera to get a screenshot of the console before rebooting it when it happened, and we were going from his memory to describe what happened. It's been 5 months (a 3 kernel upgrades) since then, and it hasn't happened again, and that machine's been under pretty serious load the entire time. :) I would just go ahead and close this out as unreproducable or something. Okay. I suspect this will be fixed by a patch added to RHEL4 to make rwsems interrupt-safe, assuming it wasn't caused indirectly by some other bug. This patch will be in RHEL-4 U2. Let us know if it happens again. |
