Description
The DB service stops from time to time but non-periodic (estimated mostly between 11pm and 9am) with the following error:
2019-03-28 23:31:08 0x7ff4dc62d700 InnoDB: Assertion failure in file /home/buildbot/buildbot/build/mariadb-10.2.23/storage/innobase/rem/rem0rec.cc line 574
|
InnoDB: We intentionally generate a memory trap.
|
InnoDB: Submit a detailed bug report to https://jira.mariadb.org/
|
InnoDB: If you get repeated assertion failures or crashes, even
|
InnoDB: immediately after the mysqld startup, there may be
|
InnoDB: corruption in the InnoDB tablespace. Please refer to
|

|
InnoDB: about forcing recovery.

|
This could be because you hit a bug. It is also possible that this binary
|
or one of the libraries it was linked against is corrupt, improperly built,
|
or misconfigured. This error can also be caused by malfunctioning hardware.
|
|
|
To report this bug, see https://mariadb.com/kb/en/reporting-bugs
|
|
|
We will try our best to scrape up some info that will hopefully help
|
diagnose the problem, but since we have already crashed,
|
something is definitely wrong and this may fail.

key_buffer_size=134217728
|
read_buffer_size=131072
|
max_used_connections=234
|
max_threads=752
|
thread_count=273
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1783435 K bytes of memory
|
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out

where mysqld died. If you see no messages after this, something went

terribly wrong...

- The DB node which crashed at first (db1b) tonight, was set up yesterday (running 10.2.23).
- The second server (db1c) crashed 70 seconds later after becoming the primary DB node and during the reconnect/resync (SST) of db1b (last update 3 weeks ago from 10.2.14 to 10.2.22)
- The third DB node db1a wasn't running since the weekend and was therefore not involved in tonights crash
If seems that the processes keep some kind of running but the service info (systemctl status mariadb.service) are in a failed state and nobody can connect or use the db services. Furthermore the process has to be killed manually.
After that I could rebuild the Cluster by creating a new Galera Cluster (galera_new_cluster) from the most advanced node.
