[AMBER] Ptraj problems

I am trying to generate pdb snapshots using ptraj. I am running into a very strange issue. When I try to generate the snapshots by submitting a ptraj job to LSF (using bsub), I have very weird snapshots (the bonds are messed up). But when I use the exact same command and run it on the local node, it works perfectly.

My trajectory is an explicit solvent trajectory. I strip the solvent (chloroform) and then generate the snapshots. The input file is shown below:

-------------------------------
trajin a.x 1 40000 100

strip :CL*

center :1-84 mass origin
center :1-84 mass origin
image origin center

trajout pdb pdb nobox
--------------------------------

When typing the command, I use:
ptraj prmtop < input_file (shown above)

When submitting to LSF, I enter the previous command in a script file and submit it using bsub.

Any comments will be very helpful. Thank you.
