Hi,
We had also the problem of cream disabled due to number of gridftp
session. We found out that the GLOBUS_PORT_RANGE was not fully opened on
this cream resulting on gridftp failing on timeout (but lasting quite long).
After correct port opening, the problem was solved. Probably not the
problem in your case but it is always worth to check.
Cheers,
Edith
