Sure.
There were 5816 project related tables, that were all initialized with the following entries:
I kicked those entries from the logfile of galera, which is appended next.
It looks like an external script/command sent SIGTERM to the server ("Normal shutdown"). Do you happen to know if there's any script/command that could be shutting down the server?
Both binaries (standard and debug version) are started via the default start-script that ships with ubuntu 16.04
