Something at the OS level is blocking the mdb memory allocation. This same issue does not occur on other SLES11 installations we have, so I'm somewhat at a loss to explain it.

Just to follow up, this is specific to SLES11, and its ulimit -v setting. What is odd, is I only see it happen on some SLES11 machines. It happens at both SP1 and SP2 on the machines where it occurs. It doesn't happen on other machines that are SP1 or SP2. So why some SLES11 system honor ulimit -v and others don't is beyond me, but at least a root cause is known.
