lock_dlm: Assertion failed on line 428 of file dlm/lock.c
Last modified: 2010-01-11 22:09:05 EST
Description of problem: Kernel panic in dlm
Version-Release number of selected component (if applicable)
Steps to Reproduce:
1. service nfs stop
2. service nfs start
3. service network stop
No kernel panic
We need additional information in order to make progress on this one, including
configuration, message logs and the full console messages/stack trace when this
problem occured. Also, how reproduceable, which version of the rhel4 kernel, etc.
If the network fails/stops while gfs is in use, then gfs will panic
in the spot shown above. That's the designed/expected behavior.

kdb information for kdb panic
In most datacenters, spurious network outages happen, This should NOT cause
kernel panics. We have seen this failure even on small private networks.
