It was done multiple times,
even more: system was recreated by mkfs.
Still the same behavior...

You may want to run a full fsck on the fs.

Hi,
After upgrading ocfs2 my cluster is instable.
At least ones per week I can see:
kernel panic: Null pointer dereference at 00048
o2dlm_blocking_ast_wrapper + 0x8/0x20 [ocfs2_stack_o2cb]
stack:
dlm_do_local_bast [ocfs2_dlm]
dlm_lookup_lockers [ocfs2_dlm]
dlm_proxy_ast_handler
add_timer
..
After that sometimes deadlock happens on another nodes. Entire cluster
restart solve the issue.
I see in log:

Additionaly ~4 times per day I see:

I currently use kernel 3.4.2
my filesystem has been created with:
-N 8-b 4096 -C 32768 --fs-features
backup-super,strict-journal-super,sparse,extended-slotmap,inline-data,metaecc,xattr,indexed-dirs,refcount,discontig-bg,unwritten,usrquota,grpquota
Could you tell me what could make my system instable? Which feature ?
Thanks for any help
Pawel
