TuGraph Server stopped in Docker while reporting 'UpdateDerivedVars is too Busy!'

[jqlin2019]

Environment:

• OS: Ubuntu 18.04.5 LTS
• TuGraph-DB Version 3.5.0
• Docker Image Version: tugraph/tugraph-runtime-centos7:3.5.0

Describe the bug

20240109080520.768: [StateMachine] bvar is busy at sampling for 2 seconds!
20240109084356.783: [StateMachine] GlobalUpdate is too busy!
20240109084453.686: [StateMachine] UpdateDerivedVars is too Busy!

I restarted the server after a few seconds.
The log was never seen before, what does that mean?
ls there too many update queries?

You can see the similar issue in brpc. These logs mean that the machine resources are too tight, causing the related threads of bvar::detail::SamplerCollector to be unable to obtain the cpu. So you can choose a machine with more resources.

You can see the similar apache/brpc#1239 in brpc. These logs mean that the machine resources are too tight, causing the related threads of bvar::detail::SamplerCollector to be unable to obtain the cpu. So you can choose a machine with more resources.

Thanks for your help.
I just restarted the docker containter with command docker restart containter_name.
There were some resource-intensive programs running on the machine at that time, I will pay attention to them.
