Subject: AMBER: Invalid Digit "*"

Dear AMBER users,

I try running a stepwise MD simulation on a fairly small molecule at
310 K in explicit solvent (TIP3).
This has been successful for about 35 ns. Then, however, when picking
up with the .restart file of a preceding MD-step, I get the following
error:

1525-097 A READ statement using decimal base input found the invalid
digit '*' in the input file. The program will recover by assuming a
zero in its place.

And indeed, the .restart file contains the lines:

  16.6512311 718.7753828 60.1922010************ 437.3638316-157.8253684
************ 436.6824416-157.6552365-999.7181769 437.0206293-158.5502830

I tried extracting a single frame of the .mdcrd file of the preceding
MD-step and creating a .restart file from it (using ptraj).
When picking up with that .restart file, the error is the same with
the only exception, the the invalid digit is a dot "." (which doesn't
make sense, since dots are supposed to be there).

Has anyone seen this before?
Thanks in advance for your help,

Gert
