OK< then what sort of problems did you actualyy see?
Running what commands, what was the error, or problem?



We have modified gm_basic in order to send messages of user defined
length (and user defined number of messages). We experienced problems
when sending 1024bytes (or 2048bytes) messages (i.e. 8 messages).
Sometimes the host receives all the GM_PEER_RECV_EVENT (i.e. 8) but not
all the GM_SENT_EVENT (i.e. 6) and then it receives GM_NO_RECV_EVENT all
the time. The behaviour of the test program changes when we activate
DEBUG (or when we include more printfs), in this case it runs perfectly.

Now gm_allsize works fine.

We understand that since changing gm_basic program can introduce some
race conditions, solving the problem can be very difficult. If you are
interested in, we can pass you the modifications we have done in order
to detect the possible bug.

P.S. We are runing GM version 1.2pre16 on a SuSE 6.1 Linux distribution
with kernel 2.0.36 with PII processors.
