脚本宝典收集整理的这篇文章主要介绍了php-fpm – PHP FPM一直挂着，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。
日志中包含以下内容：
[15-sep-2014 10:17:46] WARNING: [pool www] child 10135 exITed on signal 11 (SIGSEGV - core dumPEd) after 15.512406 seconds From start [15-Sep-2014 10:17:46] NOTICE: [pool www] child 10138 started [15-Sep-2014 10:18:02] WARNING: [pool www] child 10138 exited on signal 11 (SIGSEGV - core dumped) after 15.657950 seconds from start [15-Sep-2014 10:18:02] NOTICE: [pool www] child 10166 started [15-Sep-2014 10:18:20] WARNING: [pool www] child 10212 exited on signal 11 (SIGSEGV - core dumped) after 10.192596 seconds from start [15-Sep-2014 10:18:20] NOTICE: [pool www] child 10214 started [15-Sep-2014 10:19:08] WARNING: [pool www] child 10216 exited on signal 11 (SIGSEGV - core dumped) after 42.754452 seconds from start [15-Sep-2014 10:19:08] NOTICE: [pool www] child 10242 started [15-Sep-2014 10:20:22] WARNING: [pool www] child 10332 exited on signal 11 (SIGSEGV - core dumped) after 14.862183 seconds from start [15-Sep-2014 10:20:22] NOTICE: [pool www] child 10494 started [15-Sep-2014 10:20:48] WARNING: [pool www] child 10494 exited on signal 11 (SIGSEGV - core dumped) after 26.415409 seconds from start [15-Sep-2014 10:20:48] NOTICE: [pool www] child 10498 started [15-Sep-2014 10:32:48] WARNING: [pool www] child 11718 exited on signal 11 (SIGSEGV - core dumped) after 21.319360 seconds from start [15-Sep-2014 10:32:48] NOTICE: [pool www] child 11720 started
每次发生这种情况时,最后一次记录都类似于
[15-Sep-2014 11:01:34] WARNING: [pool www] server reached max_children setting (50),consider raising it
这是切诺基同时的连接,它甚至不是尖峰……
我尝试过动态,固定的按需,没有任何变化.无论我设置什么max_children它最终都会死掉.
为什么它不能恢复我不知道,但现在要切换到其他东西或制作一个每30分钟重启FPM的crontab
服务器
