"Timeout waiting for node-program to connect" error, only sometimes

Hello,

I have been running NAMD on our linux cluster fairly successfully.
(NAMD_2.6_Linux-i686). However, once in a while, NAMD crashes with the
following error:

#########
Charmrun> error 22 attaching to node:
Timeout waiting for node-program to connect
#########

The hardware is Dell PowerEdge 2950, 2x 2,66Ghz Intel Woodcrest CPUs, 8 GB
Ram. So that is 4 cpus per node. The jobs in question run on 8 nodes (32
cpus)

A more detailed overview of the cluster hardware is available here:

Are there any hints why this might be happening ?

Thank you,

-Himanshu
