      Description

      My situation looks very similar to this Percona issue, resolved 2019: https://jira.percona.com/browse/PXC-2127 .

      I have a 3-node cluster, stop a node gracefully:

      • mysqld and mysqld_safe do not die.
      • mysql.pid remains
      • mysql-error.log shows shutdown is in progress, lots of Applier threads are killed.
      • grastate.dat looks OK, bootstrap: 0, reasonable seqno.
      • login attempts fail
      • kill -TERM <mysql_pid> doesn't have any effect
      • kill -9 <mysql_pid> does !
