OMSA 7.1 and high load average

Hi,

Just downloaded and installed OMSA 7.1 on Dell R310 and Dell R510, both running RHEL6. As soon as OMSA processes were started the load average on system went high. Restarting services didn't help.

Is this a known issue? I found this sissue happened with 6.5 version as well so I had stopped OMSA for a while but 7.1 came out in July-12 and I thought this issue might have been taken care of, but it doesn't look like that.
