硬盘空间不够。修改一下cache设置。

如果你记录了cache.log的话，你看一下你的filedescriptor是多少？缺省为1024，如果你的服务器比较繁忙，需要增大这个值！！

Configuring file descriptors on Linux is a little complicated. You must edit one of the system include files, and execute some shell commands before compiling and running Squid. Start off by editing the file /usr/include/bits/types.h. Change the value for _ _FD_SETSIZE as follows:

#define _ _FD_SETSIZE    8192
Next, increase the kernel file descriptor limit with this command:

# echo 8192 >; /proc/sys/fs/file-max
Finally, increase the process file-descriptor limit in the same shell in which you will configure and compile Squid:

sh# ulimit -Hn 8192
This command must be executed as root and only works from the bash shell. There is no need to reboot on Linux.
