@walkor In heavy load how strace can be usable? |
I see in a business worker when CPU usage is 100% ,
and when CPU usage is higher than 90% I see this message logs at very high rate
|
It looks like a large number of interface calls caused the high load. |
What is |
For examples |
@walkor How can I reduce interface calls?? my load is really high |
Maybe some endless loop happened in the code logic that wasted all of the cpu resource,this situation can use |
@farwish I know that is is not infinitive loop . because CPU usage get down after a while |
I have 8 machine and run in each machine 10 gateway and 10 business worker
I have heavy loads , and have a bad problem
In each machine CPU usage of all gateways is same , when in a single machine , CPU usage of gateways reaches 100% Whole system (All users in all servers) hangs and not works , even when other machines CPU usage of gateways and business worker is 10-30%
Currently I'm using
stream_select
, I think when a business worker send message to gatway with 100% CPU usage , The PHP locked on the line and with timeout skip from the line ? Right? or not?Where is problem? How to solve?
