Description RHEL Program Management 2009-08-04 08:14:29 UTC
This bug has been copied from bug #508829 and has been proposed
to be backported to 5.3 z-stream (EUS).

Comment 3 Jiri Pirko 2009-08-05 08:59:28 UTC
in kernel-2.6.18-128.5.1.el

Comment 5 Nate Straz 2009-08-19 21:57:54 UTC
Tested and verified on 2.6.18-128.5.1.el5.

Test steps:
1. configure cluster w/o fencing methods
2. service cman start
3. service clvmd start
4. from nodeA, cman_tool kill -n nodeB
5. on nodeB run lvs
6. check top on nodeB for dlm_send using 99% of CPU
7. check slabtop on nodeB for TCP slab growth (it should not)
