Description
Hello Team
We are facing many restart in the DBs. the last one was yesterday, as checked in the mysqld.log, the DB got signal 11 (SIGSEGV) that's why it was restarted it could be a bug. see details below and the version of mariadb (see attached the complete logs)
250513 13:20:17 [ERROR] mysqld got signal 11 ;
|
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=67108864
|
read_buffer_size=131072
|
max_used_connections=23
|
max_threads=802
|
thread_count=37
|
It is possible that mysqld could use up to
|
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1831964 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...
