Please answer these questions before submitting your issue.

1. What did you do? If possible, provide a simple script for reproducing the error.

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。

/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
