问题描述
我跑在PHP真正的长期任务。这是一个网站履带式和它要有礼貌和睡眠，持续5秒每页为prevent服务器过载。脚本开头：
I'm running really long task in php. It's a website crawler and It has to be polite and sleep for 5 seconds each page to prevent server overloading. Script starts with:
ignore_user_abort(1);
session_write_close();
ob_end_clean();
while (@ob_end_flush());
set_time_limit(0);
ini_set('max_execution_time',0);
几个小时后（3-7h之间）脚本死亡，没有任何明显的原因。
我检查
After few hours (between 3-7h) script dies without any visible reason.I've checked
- Apache的错误日志（无）
- php_errors.log（无）
- 错误输出（调试输出的10 578 467b，没有错误）
- 内存消耗（稳定，3M左右从
memory_get_usage（真）检查每5秒，限制设置为512M）
- apache error log (nothing)
- php_errors.log (nothing)
- output for errors (10 578 467b of debug output, no errors)
- memory consumption (stable, around 3M from
memory_get_usage(true)checked every 5 sec, limit set to 512M)
这不是浏览器，因为我是用wget和Chrome浏览器检查与类似的原因。
输出将被送到每2-3秒的浏览器，所以我不认为这是错+ I忽略用户中止。
It's not browser, cause I was using wget and chrome to check with the similar reason.Output is sent to browser every 2-3 seconds, so I don't think that's the fault + I ignore user abort.
是否有任何其他地方我可以检查发现的问题？
Is there any other place I can check to find the issue?
推荐答案
我觉得有一个在你的脚本，而不是Apache。
I think there's a problem in the rest of your script, not Apache.
尝试分析使用与应用程序光探查如并记录，可能是
Try profiling your application using the register_tick_function with a light profiler like this and logging the memory usage, may be that.
