Post firmware single clients

Halfway though the transfer the speed was cut in half.

01/11 20:16:34   Net In: 11.824 Gb/s   Avg: 16.476 Gb/s 99.90% ( 00s )
After the transfer of the files was complete FDT continued to report line like such:

01/11 20:16:30   Net Out: 11.686 Gb/s   Avg: 16.490 Gb/s 99.54% ( 03s )
01/11 20:16:35   Net Out: 11.770 Gb/s   Avg: 16.459 Gb/s 100.00% ( 00s )

01/11 20:17:00   Net Out: 0.000 b/s   Avg: 15.945 Gb/s 100.00% ( 00s )

until eventually killed.

The problem with half open connection was eliminated with the firmware upgrade:

tcp        0      1 ::ffff:10.20.3.104:54008    ::ffff:10.20.3.101:54321    SYN_SENT    5684/java
was fixed by moving to the 2.11.500 firmware version for the Mellanox CX3.

Using a single writer thread the transfer was completely stable.
