[mpich-discuss] [mpich2-dev] In direct memory block for handle type REQUEST, 8 handles are still allocated

[Hisham Adel]

Thanks for your reply. I found where is the problem. 

I use the 3 MPI_Send function more than one time, at the end node I don't receive all the sent data.

That is why I got these message; the program terminate without finishing the request.

Thanks for your help.

Regards,
Hisham

Depends on what handles are leaking. If you have MPI requests, you should either Test/Wait on them or free them with Request_free. Similarly, communicators, windows, and files all have its own free'ing routines.

Do you have a test program that shows this problem?
