[Pacemaker] error: qb_ipcs_us_connection_acceptor: Could not accept client connection: Too many open files (24)

[Nikola Ciprich]

Hi,

I'd like to ask whether somebody met similar bug:

On one of the test two node clusters, node suddenly hung, and cib started
spawning following messages:

error: qb_ipcs_us_connection_acceptor: Could not accept client connection: Too many open files (24)

in lsof, I see over thousand of opened /dev/shm files:

cib        5737 hacluster  DEL       REG               0,14             2615869 /dev/shm/qb-cib_rw-control-5737-25733-179
cib        5737 hacluster  DEL       REG               0,14             2545021 /dev/shm/qb-cib_rw-control-5737-4605-178
cib        5737 hacluster  DEL       REG               0,14             2410274 /dev/shm/qb-cib_rw-control-5737-1925-180
cib        5737 hacluster  DEL       REG               0,14             2545640 /dev/shm/qb-cib_rw-control-5737-8828-177
cib        5737 hacluster  DEL       REG               0,14             2495467 /dev/shm/qb-cib_rw-control-5737-2054-174
cib        5737 hacluster  DEL       REG               0,14             2434602 /dev/shm/qb-cib_rw-control-5737-8659-176


and also sockets:

cib        5737 hacluster 1003u     unix 0xffff880eaefee000      0t0   13885836 socket

cib        5737 hacluster 1007u     unix 0xffff880eb7764000      0t0   13911546 socket
cib        5737 hacluster 1008u     unix 0xffff880a7f579400      0t0   13847938 socket
cib        5737 hacluster 1009u     unix 0xffff880a7f57e000      0t0   13883333 socket

OS is latest centos6 (RHEL6 clone), running x86_64 3.0.87 kernel

another important packages:

pacemaker-1.1.8-7.el6.x86_64
cluster-glue-1.0.5-6.el6.x86_64
clusterlib-3.0.12.1-49.el6.x86_64

Any idea on what this could be? Is this some known bug?

with best regards

nik
