      Description

      TrueNAS-SCALE-21.02-ALPHA.1

      On a regular but unpredictable basis, a middlewared (zettarepl) process turns to a zombie on my system, meaning that all replication tasks are broken (whether scheduled or manually triggered, they show RUNNING in the web UI but they are not actually running and no data is transferring). Sending a SIGCHLD to the parent middlewared process does not kill the process, but service middlewared stop; service middlewared start or a reboot does.

      I'm attaching a debug file as a private attachment shortly, if there's anything else which may help troubleshoot then let me know - I can't reproduce this on demand, but it reproduces itself with some regularity.
