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 Test[b13f]: dat_psp_create #6 error: DAT_CONN_QUAL_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #0 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED Test[b13f]: dat_evd_free (creq) error: DAT_INVALID_STATE DAT_INVALID_STATE_EVD_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #1 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED Test[b13f]: dat_evd_free (creq) error: DAT_INVALID_STATE DAT_INVALID_STATE_EVD_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #2 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED Test[b13f]: dat_evd_free (creq) error: DAT_INVALID_STATE DAT_INVALID_STATE_EVD_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #3 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED Test[b13f]: dat_evd_free (creq) error: DAT_INVALID_STATE DAT_INVALID_STATE_EVD_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #4 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED Test[b13f]: dat_evd_free (creq) error: DAT_INVALID_STATE DAT_INVALID_STATE_EVD_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #5 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED Test[b13f]: dat_evd_free (creq) error: DAT_INVALID_STATE DAT_INVALID_STATE_EVD_IN_USE Test[b13f]: Warning: dat_ep_disconnect (abrupt) #6 error DAT_INVALID_STATE DAT_INVALID_STATE_EP_UNCONNECTED 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?
