Full kernel oops messages
This *might* be fixed in the u2 beta kernel. Can you please give 2.6.9-18.EL a whirl: http://people.redhat.com/~jbaron/rhel4/. thanks. Sorry, I cannot let a beta kernel loose on our production fileserver... When are the U2 patchwork released as production? fair enough, eta is currently about 2 weeks. I'm sorry to say, that this new kernel didn't solve our problems. We have reason to believe, that this problem occours when there is high io, because it ususally happens when our backup system (tsm) is running, even in memory efficient mode (we have verified that the process doesn't consume more than 100M resident memory). We do have a brand new kernel dump, if you're interested. I'm also attaching the new netdump log... Created attachment 120447 [details]
Netdump log of oops from crash at 2005-10-27
We are still experiencing random crashes on our production machines, so this issue is of high importance to us. From one of the latest crashes, yesterday, I've got a kernel dump through netdump, and a log file, if you are interested in this. We are highly suspecting autofs4 to be the catalyst for this behaviour, since the problem has gone away on another server, after we disabled autofs. However, it is not possible to diable autofs on all servers, since the one that crashed yesterday is a web server that needs to mount public_html catalogues on user accounts on other nfs servers.

Ooops message from the syslog
We've just seen this issue on a production fileserver that we recently
transitioned to RHEL4. It's running kernel 2.6.9-22.0.2.ELsmp on dual Athlon
MP 1900+ with 2GB of RAM. This machine also uses autofs fairly heavily.
note that this is very likely a duplicate of 173843, which we are actively working....thanks. (In reply to comment #11) > note that this is very likely a duplicate of 173843, which we are actively > working....thanks. I agree--I just noticed this following in my syslogs a few minutes before the crash, which seems to be consistent with Bug 173843: Apr 10 22:07:14 fileserver kernel: VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice day... Apr 10 22:07:14 fileserver kernel: VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice day... Any ballpark yet for a resolution on Bug 173843? This does appear to be a duplicate of 173843, so I will close it as such. If it does turn out to be a duplicate, then we can reopen this report and investigate it more then. *** This bug has been marked as a duplicate of 173843 *** |
