That certainly is strange behavior. One reason this might be happening
is you are directing your input file in as standard input, which in
the context of having to submit with another command (mpirun) could be
causing strange behavior; the ptraj input file might be redirected to
mpirun instead of ptraj. In particular this seems odd:

Try running ptraj without the redirect operator:
mpirun -as single -np 1 -maxtime 360 ptraj fzd5-7_w.prmtop fzd5_w_ca.calc_rms
Also, I would recommend you upgrade to AmberTools 1.4
(
http://ambermd.org/#AmberTools). There are significant performance
improvements when compared to amber 10 ptraj. If you do decide to run
AT1.4, be sure to apply all bugfixes after downloading
(
http://ambermd.org/bugfixesat.html).
Let me know if you have any more issues - good luck!

About compillers I am not sure, but this is single processor run, not parallel, mpirun I just use to submit it in the queue on cluster according to description on how single processor mode should be run there. System has about 250 amino acids, four trajectories, each 5 ns. Only rms Ca calculation for now. When I don't use mpirun - on central node it takes just few minutes to the task to be completed, but there is pretty much trajectories and running software on central node is not tolerated by administration and from other side I want to put all trajectories analysis in the shell script.
