squid troubleshooting

1.Running out of filedescriptors

If you see the Too many open files error message, you are most likely running out of file descriptors. This may be due to running Squid on an operating system with a low filedescriptor limit. This limit is often configurable in the kernel or with other system tuning tools. There are two ways to run out of file descriptors: first, you can hit the per-process limit on file descriptors. Second, you can hit the system limit on total file descriptors for all processes.

	Squid 2.0-2.6 provide a ./configure option --with-maxfd=N
	Squid 2.7+ provide a squid.conf option max_filedescriptors
	Squid 3.x provide a ./configure option --with-filedescriptors=N
