I have a problem while using laravel with swoole on php 8.1.Some requests finished with HTTP 408 sometimes. Then when I looked at the log file, I saw the following error.
[2022-07-29 08:59:52 $28.0] WARNING Server::check_worker_exit_status(): worker(pid=49, id=4) abnormal exit, status=0, signal=9
then I watched all the processes with "strace" command. I saw the worker killed by manager process. Logs are bellow:
ps -aux

www 1608 0.2 1.3 427668 52384 ? S 13:19 0:00 swoole_http_server: worker process
strace.log:
54 13:27:40.909415 kill(1608, 0) = 0
54 13:27:40.909598 kill(1608, SIGKILL) = 0

65 13:27:40.944400 rt_sigreturn({mask=[]}) = 1608
I tryed a lot of things but not fixed this problem. How can i deal it?
