APC正常运行时间很短 [英] APC Uptime is very low

问题描述

这是我的服务器信息:

• APC版本:3.1.9
• PHP版本:5.2.17
• 服务器:LiteSpeed
• PHP:DSO.
• cPanel:是的.
• WHM:是的.

我很少打开apc.php，我通常在高峰流量下打开它，每天大约3-6次. 我大部分时间都在打开它，正常运行时间很短，范围从20分钟到5个小时不等.但是，我从未收到过任何错误电子邮件，例如Litespeed自行重新启动时.

I rarely open my apc.php, i usually open it on my peak traffic, about 3-6 times a day. Most of the time i open it, uptime is low, ranged from 20 minutes to 5 hours. However i've never received any error e-mail such as when my Litespeed restarts by itself.

• APC内存使用率很低，为10-25％.
• 碎片也很低，< 1％.

这是我的APC设置.

apc.cache_by_default    1
apc.canonicalize    1
apc.coredump_unmap  0
apc.enable_cli  1
apc.enabled 1
apc.file_md5    0
apc.file_update_protection  2
apc.filters 
apc.gc_ttl  3600

apc.use_request_time    1
apc.user_entries_hint   4096
apc.user_ttl    7200
apc.write_lock  1

我可以做些什么来延长正常运行时间吗? 我的另一个小问题是，当APC重新启动时，其缓存是否被刷新了?

Is there anything i can do to make uptime longer? And my other little question is, when APC restarts itself, is its cache flushed?

推荐答案

在litespeed论坛上询问后，这是因为我的Litespeed似乎每1-2小时重新启动一次.我的托管人说，LiteSpeed每1-2小时重新启动一次是为了在处理统计信息时轮换访问日志.我的服务器上的管道日志记录已启用，可以解决此问题.

After i asked on litespeed forum, it is because my Litespeed seems restarted every 1-2 hours. My hosting said that the reason that LiteSpeed restarts every 1-2 hours is in order to rotate the access logs when processing statistics. Piped logging on my server has been enabled to fix this issue.
