Description Martin Juricek 2011-10-18 10:24:56 UTC 
Description of problem:

I hit this problem when testing bz739084. Simple bash loop with cman_tool join and cman_tool leave commands was run on all cluster nodes (3-node cluster, ia64 arch). As a result, core files are generated in /var/log/openais on all nodes.


Version-Release number of selected component (if applicable):
openais-0.80.3-22.el5_3.17
openais-0.80.3-22.el5_3.16

How reproducible:
100%

Steps to Reproduce:
1. enable creating of core files
2. run simple bash loop with cman_tool join/leave on all cluster nodes:
   ( while true; do cman_tool join; cman_tool leave; done )
3. core files are generated in /var/lib/openais
  
Actual results:
-core files generated

Expected results:
-no core files

Additional info:
