Check register_globals setting on the two servers. Maybe something
writes over your GET/POST variables or vice versa...
Also, how do you handle MySQL errors? The behavior you are observing
is consistent with queries not being executed (which could happen when
your MySQL server is overloaded). The script tries to connect to the
MySQL server, gets an error, fails to execute the queries due to no
connection and redirects...

No, but it is possible that the hosting company does. It is unlikely
though, because the problem is intermittent...
