      I was unable to log in to the web UI, so I ssh'd in and got this after logging in

      Traceback (most recent call last):
        File "/usr/local/sbin/hactl", line 171, in <module>
          main(args.command, args.q)
        File "/usr/local/sbin/hactl", line 17, in main
          client = Client()
        File "/usr/local/lib/python3.8/site-packages/middlewared/client/client.py", line 281, in __init__
        File "/usr/local/lib/python3.8/site-packages/middlewared/client/client.py", line 124, in connect
          rv = super(WSClient, self).connect()
        File "/usr/local/lib/python3.8/site-packages/ws4py/client/__init__.py", line 216, in connect
      ConnectionRefusedError: [Errno 61] Connection refused

      So I restarted the middlewared from the shell, and the UI came back, then I had this pop up as an alert 


      The following system core files were found: python3.8.core. Please create a ticket at https://jira.ixsystems.com/ and attach the relevant core files along with a system debug. Once the core files have been archived and attached to the ticket, they may be removed by running the following command in shell: 'rm /var/db/system/cores/*'.

      I grabbed the core file from the server but it's 2.8 GB (400 MB compressed) so I can't upload it here. Happy to provide it though if there's a file host you can recommend.

      My knowledge of gdb is minimal but here's what I was able to get from it
