[Linux-cluster] gfs_glock_is_locked_by_me assertion failures



Hi,

In our five node cluster running the same software version on all 
machines, two of them have started to emit assertion failure messages:

Feb 26 13:54:47 web0 kernel: GFS: fsid=kfki:services.4: warning: assertion
"gfs_glock_is_locked_by_me(ip->i_gl)" failed
Feb 26 13:54:47 web0 kernel: GFS: fsid=kfki:services.4:   function = gfs_readpage
Feb 26 13:54:47 web0 kernel: GFS: fsid=kfki:services.4:   file =
/services/src/2.6.23.16/cluster-2.01.00/gfs-kernel/src/gfs/ops_address.c, 
line = 279
Feb 26 13:54:47 web0 kernel: GFS: fsid=kfki:services.4:   time = 1204030487

One of the machines in question has been rebooted today, the other one has 
been running for several days.

How could I debug what is the reason of the problem?

Best regards,
Jozsef
