10.6.5
-
Debian Stretch on LXC
Description
Our database seems to crash for no apparent reason. This has happend to us 4 times on different nodes within the last 3 weeks. There is no log entry system-wide other than the mysql error.log. Resources, storage capacity, hardware - everything checks out just fine. We run Version 10.6.5 for almost 6 months now, so we find it odd that a problem within MariaDB hits us now in such succession.
The problem seems to occur on one specific table only for all occurences. Every query, regardless if it is a select, update or just a check table against the table stalls the connection and it hangs.
We don't have a replication setup running, nor have we changed much within the default configuration for MariaDB.
How can we help to narrow down the problem?
Update:
Somehow we guess, MDEV-19783 may be part of the problem, but then again the servers in question were rebuild from scratch while migrating to version 10.6.5. After clarification that was not the case, in fact we hardcopied the datafles like ibdata1 etc to the new server, so we might have copied some corruption with it aswell.

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.

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.

Server version: 10.6.5-MariaDB-1:10.6.5+maria~stretch-log
|
key_buffer_size=16777216
|
read_buffer_size=131072
|
max_used_connections=154
|
max_threads=242
|
thread_count=17
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 549251 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...
