Can you elaborate on the multiple sends ? Are they outstanding

they from a single or multiple threads ?
No they are sending sequentially(mutex enabled) no concurrency but timeout for
umad_recv is 100ms.
Can you try increasing that to see if there is some threshold where it
works more reliably ? Does it work better at say 200 msec (as you said
your rate was 4/sec) ? The default timeout used in the diags is 1 sec.
yes, I tried increasing it upto 3000ms but condition not improved much (it
*reduced* timeout failures but *no reduction* in recv_fail and this piling up
number of request per second too at client side). Also I tried same code on two
separate subnet and similar problem come across. Could be a network issue but is
it a fact that GMP request takes much more time then SMP request (for ideal
subnet) ?
Looks like there are some issues here to debug in your subnet. It might
help to clear the counters and see what is actively going on to isolate
these issues. This could factor into those other errors you are seeing.
