crash looks similar to what patch
https://oss.oracle.com/pipermail/ocfs2-devel/2012-January/008469.html
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.
regarding ERROR: status = -17 what storage do you use? could be due to
stale data.

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

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:

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
