Hello everyone,

I'm facing a critical issue with MariaDB 10.4.34 running on CentOS 7. The database server crashes frequently, approximately every 20 minutes. I'm reaching out for help to understand the core dump analysis and guidance on upgrading to the latest stable version to resolve these crashes.

System Details:

MariaDB Version: 10.4.34
Operating System: CentOS 7 (x86_64)
Memory: 6 GB RAM
Disk Space: 400 GB SSD
Issue Description:

MariaDB server crashes frequently with the following signal:

vbnet
Copy code
Core was generated by `/usr/sbin/mysqld'.
Program terminated with signal 6, Aborted.
#0 0x00007fef2d2c0aa1 in pthread_kill ()
from /lib64/libpthread.so.0
I attempted to analyze the core dump using gdb and got the following backtrace:

Code:
(gdb) bt
#0 0x00007fef2d2c0aa1 in pthread_kill ()
from /lib64/libpthread.so.0

#12 0x00007fef2c7d6b0d in clone ()
from /lib64/libc.so.6

Steps Taken

Analyzed Core Dump:

Used gdb to generate the backtrace.
Identified the signal causing the crash (signal 6, Aborted).
Checked Logs:

No relevant error logs found in /var/log/mysql/error.log or /var/log/mariadb/mariadb.log.

Reviewed System Resources:
Memory seems adequate with 4.2 GB available out of 6 GB.
Disk space utilization is at 16% of 400 GB.
Tried Basic Fixes:

Ensured all packages are up to date.
Restarted MariaDB service multiple times.
Attempted to Apply Debugging Info:

Encountered issues with debuginfo-install command while in gdb:

Core Dump Analysis:

Could someone help interpret the backtrace and suggest specific causes or fixes for the frequent crashes?
Upgrading MariaDB:

Detailed guidance on how to upgrade MariaDB to the latest stable version on CentOS 7.
Any precautions or steps to ensure a smooth upgrade process without data loss.

-Any additional logs or diagnostics that I should collect?
-Recommendations for configuring MariaDB to avoid such crashes in the future.
Your assistance is greatly appreciated as this issue is impacting our production environment. Thank you in advance for your time and help
