System is going to auto reboot or cpu stall or hang

[harry6264]

Hi All,

We recently migrated debian from CentOS and we are seeing cpu yield is more in Debian (> 4 uSec) compared to CentOS(2 uSec).
May I know why it is more ? if not, what is the configuration to check
My application was running fine on CentOS but not stable on Debian with sudden auto reboot or hang or stall issues

What debian version is this?
Your kernel is 5.10.0-25-rt-amd64, which is extremely old.
And from your dmesg above, it is also tainted, which means you have loaded some non-standard kernel module.

You will have to provide lots of details if you want any help with this, and for all intents and purposes, you may not even be running debian.

Hello,

We recently migrated debian from CentOS and we are seeing cpu yield is more in Debian (> 4 uSec) compared to CentOS(2 uSec). May I know why it is more ? if not, what is the configuration to check

You asking two different questions:

• "System is going to auto reboot or cpu stall or hang (the topic)": the current discussion I assume is for this topic
• "Cpu yield is more in Debian (> 4 uSec) compared to CentOS(2 uSec) [..] why it is more ?" : open a different discussion for this topic; if you do, please report the complete command (with output) you used to measure cpu yield and the reason you are using a "rt" kernel.

System instability can be caused by many factors, some relevant are hardware problems/failures (i.e. for auto-reboot) or system overload (for stall/hang). You can monitor your system continuously over time to find some clues as to what is happening. Your decision to install an "rt" kernel may facilitate other contributing factors.

Hope this helps.
