RH Tech support has discouraged me to upgrade a two-nodes cluster
for two reasons:
1) RHCS 4U5 packages were not released to rhn.
2) RHEL 4U5 kernel (2.6.9-55, correct me if I'm wrong) has an issue
    and therefore they suggest to wait for a following fix.

I think that 1) is no more the case. RHCS channel is, in fact, updated to
the current kernel (2.6.9-55).

For 2), I don't know. My test machines run smoothly with 4U5, but
for production machines, I'm holding the upgrade. Now I'm running
4U4 (2.6.9-42.0.10) and related cluster packages.

And you?
