[138.1891]Why is the CPU not running well

My CPU freezes for 20 minutes every 5 minutes of operation. I suspect that four processors are causing the CPU kernel to exceed 64 cores. There may be an issue with your scheduler, please check and confirm. Thank you

Why are the strategies generated every hour becoming less and less? Why is this happening? Is it something I set incorrectly?

I think, something is wrong in your setting.

The best is, if you post here your setting.

1) you can set configuration/cpu/custom number of cores higher

2) increase the amount of islands from 4 to 20 for example

Thank you, my island count is set to 20, and the CPU count is set to the default option. I tried using ZGC as garbage collection, and the settings for using ZGC are:


Option Djava. net. useSystemProxies=true

Option Djava. net. refereIPv4Stack=true

Option Djdk. tls. trustNameService=true

Option - Xmx100g

Option - XX:+UseZGC

Option - XX: ZCollectionInterval=60


After this setting, the UI of SQX did not freeze, but the number of strategies generated per hour still steadily decreased, and from the Grid perspective, there are several tasks in the background that have not ended. I don't know if this is the reason?

Is the number of policies generated per hour related to memory release and GC parameters?

It seems that there are several jobs that cannot be completed，After clicking stop for me, the UI shows that it has stopped, but the CPU load is 100%，This situation is not present in version 136. How should we adjust it?
