Resolved.
Found temporary solution after a google search.

artipc10.vub.ac.be/.../leap-second-causing-ksoftirqd-and-java-to-use-lots-of-cpu-time

lkml.org/.../203

date -s "`date`" resolved it for me.

Dell OMSA on RHEL6, high load average.
 
Hi,

To run OMSA 7.1 you need to be on RHEL6.2. Always check the support matrix
for OpenManage components. It is very important.
http://support.dell.com/support/edocs/software/smsom/7.1/en/peosom/Support_matrix.pdf
http://support.dell.com/support/edocs/software/smsom/

If the problem persists with the supported version, you can collect
sosreport and open a case with Dell tech support to investigate.

Regards,
Grzegorz
