Each reconnect generates two thread, which do not die.

Hello Konstantin,
Does the above output mean that you are using the ib_srp-backport driver
? If so, please upgrade to version v2.0.34. That version includes all
SRP initiator fixes that have been posted on the linux-rdma and
linux-scsi mailing lists for inclusion in Linux kernel v4.3.
Bart.
Hello, thanks for reply.
I build a package version 2.0.34, but problem is reproduced:
