Description Angus Salkeld 2010-12-22 23:26:11 UTC 
Description of problem:

Shared memory is leaked if corosync dies (SIGSEGV/SIGKILL...)
and there are clients connected at the time of corosync's death.

Version-Release number of selected component (if applicable):
all corosync versions

How reproducible:
100%

Steps to Reproduce:
1. start corosync
2. start any corosync client
3. killall -9 corosync
  
Actual results:
ls /dev/shm/*_buffer*
control_buffer-uxrYP7 request_buffer-6AzFFP dispatch_buffer-66Ovlf                                 response_buffer-Xd9vvx

Expected results:
ls /dev/shm/*_buffer*
