squid 日志到2G时停止工作

 

晚上收到报警短信，原来是公司squid停止工作，

上网找了一下，原因是acces.log 日志到2G了。

Thanks to Google for saving my life again as a dummy Linux administrator.

The search term “Squid Parent: child process exited due to signal 25″ led me to  who suggests that the Squid server log files (in particularly, the cache.log file) might have exceeded the Linux 2GB file size limitation! Otherwise, the Linux file system might be the culprit – run fsck command to check the file system consistency.

(The Squid v2.6 Stable 5 is running on Red Hat Enterprise Linux AS 3 using kernel version 2.4.21-4.ELsmp).

For my case, it was the cache.log that had exceeded 2GB exactly. After running > cache.log to initialize the file, the Squid Proxy server is up and working again.

To prevent this from happening again, I’ve to enable logrotate on cache.log file too. Previously, only the access.log file is logrotated, as this log file can grow up to a very big file size in just half a day – it log every lines whenever a browser loading a web page from the Web!
