This is something you need to discuss with COMSOL tech support and make sure you have a compatible cluster and that your installation is correct.
I also had trouble on my RHEL 5.8 cluster between v4.3 and v4.2a. with the new version, COMSOL could no longer work with the infiniband drivers on our RHEL cluster. They provided a workaround, but I expect it to be corrected in the future.
Your error appears to be different than this problem I was having.
