From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0) Gecko/20020623 Debian/1.0.0-0.woody.1 Description of problem: RedHat 7.2 Machines within a processing farm have begun to occasionally oops, apparently during periods of high load/activity. Typically, a number if machines(5-10) will all oops around the same time. Machines are pingable, but no other network services available. Serial console is available, and allows root login. System is up with minimal services/processes running. Anything associated with network connectivity has died. dmesg shows the following: VFS: Busy inodes after unmount. Self-destruct in 5 seconds. Have a nice day... md: recovery thread got woken up ... md: recovery thread finished ...

Any ideas on what could be going on here, or any additional steps I can take to debug this issue? Version-Release number of selected component (if applicable): kernel-2.4.18-17.7.x How reproducible: Sometimes Steps to Reproduce: Unknown, but could be related to high load and network/file activity. Additional info: dmesg shows the following on a oops'd machine: VFS: Busy inodes after unmount. Self-destruct in 5 seconds.
