Hi,

I am trying to ro perf with block size 64k and get this error, is there any configuration setup I am missing? Its works upto 8k block though.


Associating SPDK bdev Controller (SPDK00000000000001  ) with lcore 0
Initialization complete. Launching workers.
Starting thread on core 0
nvme_tcp.c: 909:nvme_tcp_pdu_ch_handle: *ERROR*: Expected PDU header length 24, got 7
nvme_tcp.c:1588:nvme_tcp_qpair_process_completions: *ERROR*: Error polling CQ! (11): Resource temporarily unavailable
Segmentation fault

Thanks
Ram

If you use RPC to create the transport via "-u 8192" , which should be removed, then it will use the default one
