Dear all,

I have a problem when using distance restraint with pmemd :
Here is one of my output files :

I already had this problem before and the bugfix.31 patch was proposed
to solve this
problem, but it seems that it does not solve the problem entirely.
As the warning is written 15 time and I work with 16 processors on
SGI Origin 3800, I guess it is due
to processors wanted to write in the same place.
This problem does not seem to affect the calculations but is still annoying.

Any help will be appreciated,
Thanks in advance,
Fabien
