[Pacemaker] pacemaker-1.1.12 - lots of Could not establish cib_ro connection: Resource temporarily unavailable (11) errors

[Nikola Ciprich]

Hello,

I'd like to ask about following problem that troubles me for some time
and I wan't able to find solution for:

I've got cluster with quite a lot of resources, and when I try to do
multiple operations at time, I get a lot of resource failures (ie
failed starts)

The only related information I was able to find is following snippet of the log:

crmd:   notice: process_lrm_event:     Operation vmtnv03_start_0: unknown error (node=v1b, call=748, rc=1, cib-update=211, confirmed=true)
crmd:   notice: process_lrm_event:     v1b-vmtnv03_start_0:748 [ Error: 'Could not establish cib_ro connection: Resource temporarily unavailable (11)'\n ]

The OCF script does not do anything special, start action basically just runs some 
python command..

Does somebody have a tip what to do with this problem, or how to debug it further?

my system is latest centos 6, pacemaker-1.1.12-4.el6, cman-3.0.12.1-68.el6,
resource-agents-3.9.5-12.

thanks a lot in advance!

with best regards

nik
