pacemaker-1.0.6 + corosync-1.1.2 crashing - SOLVED

Hi Guys,
Finally I've found where the problem was! On my testing machines,
the system was lacking separate /dev/shm tmpfs mount. While the /dev
directory is also mounted as tmpfs, so it seemingly doesn't make any
difference, there IS one: /dev is mounted with mode=755 parameter,
while /dev/shm should be mounted without it. So after I mounted it,
everything starts working like a charm! :)
While it's certainly unusual that systems lack separate /dev/shm mount,
it still might be mentioned in documentation.
anyways, thanks to all of You for Your time.
have a nice day.
nik

thanks for the bug report.

corosync should use /var/lib/corosync if /dev/shm is unavailable. This
is also what the code does. Probably needs a bit of testing around that
case.
