Perhaps the port is in use by the host TCP stack?

dapltest server will start with port 45278 and increase by client thread count
during each new client connection. If you never restart the server it will
continue to increase the listen port based on new clients connecting. If you
restart dapltest it will restart back at port 45278. I am not familiar with
iWarp CM but the error is coming from rdma_bind_addr
(EADDRINUSE|EBUSY|EADDRNOTAVAIL). I will have to defer to Steve for this error.

Subject: Dapltest test error DAT_CONN_QUAL_IN_USE
Hi All,
I was running dapltest between my client and server machines with OFED-
3.5. While running the test it dapltest server throws an error
DAT_CONN_QUAL_IN_USE if I increase number of threads and endpoints.
Dapltest server:
---------------
dapltest -T S -D chelsio1
Dapltest client:
---------------
dapltest -T T -s 102.1.1.2 -D chelsio1 -R BE -i 1 -t 16 -w 8 server SR
8192 4 client SR 8192 4
Once I run the above test i get the following error on server side and
client side stalls.
$# dapltest -T S -D chelsio1
Dapltest: Service Point Ready - chelsio1

Following link says DAT_CONN_QUAL_IN_USE error can come if rdma_cm
returns an error due to bind failure.
http://www.mail-archive.com/linux-rdma@vger.kernel.org/msg01297.html
rdma_cm from OFED-3.5 does not provide module parameter
'unify_tcp_port_space'. So, just to narrow down I installed OFED-
1.5.4.1 and ran the same test with unify_tcp_port_space=1. However with
that also I was able to reproduced the same issue.
Please note that if I decrease the numbers of endpoints to 4 then test
works fine. i.e. If I give '-w 4' instead of '-w 8' in command line
then test runs fine.
I am using dapltest version 2.0.36 which comes from OFED-3.5.
Can anyone give any pointers on this?
Thanks,
Vipul
