[ewg] Huge size for opensm process (5.7GB)

[Sandeep Dhavale]

Hello,
I have a setup where 2 nodes are connected back to back. So my subnet is basically 2 nodes.
This is RHEL6.3 setup and opensm running is

[root at intel-eva1 ~]# rpm -qi opensm
Name        : opensm                       Relocations: (not relocatable)

The opensm process has grown up and is now 5.7GB. I do not think this is normal for a subnet of size 2 nodes.

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  DATA COMMAND
15306 root      20   0 5851m 2568  692 S  0.0  0.0   0:06.04 5.7g opensm

[root at intel-eva1 ~]# ps -ef | grep  opensm
root     15306     1  0 01:04 ?        00:00:06 /usr/sbin/opensm -B -F /etc/rdma/opensm.conf.[0-9]*

One thing to notice is the /var/log/opensm.log is flooded with messages like below every 10 second:

Sep 26 12:21:58 384194 [E2BA2700] 0x01 -> osm_prtn_make_partitions: Partition configuration /etc/rdma/partitions.conf is not accessible (No such file or directory)
Sep 26 12:21:58 385098 [E2BA2700] 0x02 -> SUBNET UP
Sep 26 12:22:08 384306 [E2BA2700] 0x01 -> osm_prtn_make_partitions: Partition configuration /etc/rdma/partitions.conf is not accessible (No such file or directory)
Sep 26 12:22:08 385189 [E2BA2700] 0x02 -> SUBNET UP

Can anybody put some light on what might be wrong? Does opensm maintain the log in memory as well? I haven't put a limit on the size of the log in /etc/rdma/opensm.conf.


Thanks,
Sandeep.
