Limit on Number of qp?

[njsys]

When we use ib_send_bw or ib_write_bw with about 96 QP q=96 and n=1000, we notice out of sequence or out of buffers or packet sequence errors while running these tests between 2 different machines using mellanox ofed 5.

If we run the client and server tests both on the same machine then we observe no errors.the issue is seen only when we go across machines.

Is that an issue with the code in ibsendbw or ib_write_bw or is the issue some where else? Thanks
