使用swoole coroutine+task完成日均百万级数量耗时任务处理，在任务开启一段时间后，出现如下错误。 [2024-07-18 05:48:45 *4002142.5] WARNING Worker_reactor_try_to_exit() (ERRNO 9101): worker exit timeout, forced termination [2024-07-18 06:03:48 #4001610.0] WARNING Manager::kill_timeout_process() (ERRNO 9101): worker(pid=4002016, id=454) exit timeout, force kill the process [2024-07-18 14:24:20 ^913338.268] WARNING TaskWorker_onPipeReceive(): read(1056, 8192) failed, Error: Resource temporarily unavailable[11] [2024-07-18 14:24:20 ^913338.268] WARNING ReactorEpoll::wait(): EPOLLIN handle failed. fd=1056, Error: Resource temporarily unavailable[11] /var/log/messages 中没有异常日志，也没有出现core-dump,只是在 log_file 中出现这种WARNING

这看起来像是发送了SIGUSR1信号给worker/task进程，导致worker/task进程重启了
