The segfault is the problem. No code may segfault. If it does,
something is badly wrong.

Run a simple test - just one process. Something like

   enbd-maketest -n 1 -x /tmp/core --notest --noreload

(one server, one client).

What "remaining connections"? If those are different clients running
on the same driver, then the kernel has oopsed, since there is no
other connection between them.

A device that is not connected is not working and can tell anyone who
tries to talk to it that it is ill.  Are you maybe running in a sync
mode?  Maybe you want "-e"

     -e This option specifies that the ENBD device will transmit network
     errors almost immediately to any higher level device, such as RAID,
     that may want to be notified of them.  The flag is normally absent
     and the ENBD device will hide network errors inter=AD nally, blocking
     new requests until they can be me
