Hi Lars,

Are you sure bug fix.14 was correctly applied and the recompile worked? -
Did you make clean first?

Do you see this for every test? - Can you run one manually and report what
you see for the version information in the file header.

| GPU (CUDA) Version of PMEMD in use: NVIDIA GPU IN USE.
| Version 12.2
|
| 01/10/2013

All the best
Ross
