Comment 13 for bug 821732

Not sure these symptoms would be the same on the later versions but on Lucid I also encountered the following due to this bug:

service corosync stop - never completes. Hangs waiting for crmd to shutdown (over 6 hours without a change)
crm ra info ocf:xx:xx - hangs the crm shell
crm configure primitive p_test ocf: - hung when trying to use tab completion of ocf:<tab>
