Re: Dapltest test error DAT_CONN_QUAL_IN_USE

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

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.
