Hi,
as a part of my effort with tuning (and testing) PCMK_ipc_buffer value,
I've get into situation where all pacemaker tools start dying..
My setup:
CentOS 6 + all updates, two nodes CMAN + pacemaker cluster.
I've changed following /etc/sysconfig/pacemaker values (ipc_buffer size
as recommended by pacemaker log):
PCMK_ipc_buffer=13828900
PCMK_ipc_type=shared-mem
PCMK_STACK=cman
I've also exported all those variables using .bash_profile so they're available
to CLI tools.
Then I've populated CIB with 5000 Dummy resources. Since config commit,
all tools start aborting:
cibadmin -Ql
Aborted
Here's the backtrace:
(gdb) bt

Not sure whether this is of any help, if I could provide more information,
please let me know..
