Description Steven Dake 2010-06-24 17:26:03 UTC
Description of problem:
if corosync service is shutdown, client libraries wait 2 seconds before returning an error.  A different approach to this problem would be to set a variable in the control_buffer global area indicating the server has exited and sem_post on the all the semaphores in the system during conn_info_destroy.

Check the value of the exited flag before and after sem_wait.  If the exited flag is true, return ERR_LIBRARY

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

How reproducible:

Steps to Reproduce:
1. test case attached
2. run service corosync restart in a loop
Actual results:
two second delay if corosync is shutdown normally

Expected results:
no delay if corosync is shutdown
