*Dear namd users,

I am running namd on the following system:

Dell 1855 Linux cluster. Each node is equipped with two Intel Xeon EM64T
processors (3.6GHz) and 4 GB of memory. The nodes are connected with
Infiniband, a high-speed, low-latency copper interconnect.

After submitting a job for equilibrating a system of 7000 atoms using
NPAT, I got the following error in the log file:
