Two thing I need to mention in this issue. One, support doesn't think
anymore that it's a coro-sync specific issue, they are searching to a
driver issue or other source for this problem.
Second, I downgraded my kernel to 2.6.32-71.29.1.el6 (pre-6.1, or 6.0),
for another issue, and since I did, I don't think I saw that issue
again. I saw spikes in my cpu graphs, but I'm not 100% sure that they
are caused by this issue.
So, as a temporary work-around for this time, woule be (at your own
risks) to downgrade to 2.6.32-71.29.1.el6 kernel :
yum install kernel-2.6.32-71.29.1.el6.x86_64
