trying to address. The fix is not yet accepted because as explained
in the patch description we need to fix the master node to skip
sending BAST after receiving unlock message.<br>
<br>
regarding ERROR: status = -17 what storage do you use? could be due
to stale data.<br>

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

Additionaly ~4 times per day I see:<br>

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