We've seen the same occasionally using CentOS5/RHEL5 with jobs running
under Torque with cpusets enabled.
Never been able to explain it and the most recent case was someone
using a home compiled version of NAMD, the problem disappeared when
they started using our provided builds.
I was fixing up the running problem jobs by hand by assigning procs to
individual cores on the nodes with cpusets. :-/
