今天SQUID突然停了，用service squid start显示OK，用netstat -an |grep tcp发现没监听相应端口，ps -x | grep squid也找不到进程。

查看/var/log/squid/squid.out发现以下错误。
squid: ERROR: Could not send signal 0 to process 3275: (3) No such process
squid: ERROR: Could not send signal 0 to process 3275: (3) No such process
squid: ERROR: Could not send signal 0 to process 3275: (3) No such process

重启系统问题依然存在。因为用的硬盘很小，怀疑没空间了。df一看果然是使用100%，汗，删除了缓存腾出空间后恢复正常。
