squid故障汇总

前文：http://www.2cto.com/os/201202/119673.html

 
以下为个人总结
 
一：报错信 息：
FATAL:  Failed to verify one of the swap directories, Check cache.log
       for details.  Run 'squid -z' to create swap directories
       if needed, or if running Squid for the first time.
Squid Cache (Version 2.6.STABLE18): Terminated abnormally.
未执行squid -z命令需要执行该命令初始化cache目录，假如想观察这个过程squid -zX
 
 
Creating Swap Directories
FATAL: Failed to make swap directory /usr/local/squid/var/cache/00:
   (13) Permission denied
确认/usr/local/squid/var/cache目录的所有组成都可被squid.conf给定的 用户ID访问
 
 
 
二：
 
WARNING:squidaio_queue_request: WARNING - Queue congestion
 
IO的队列满了, ,重谝一下源代码,加大IO的 队列或换一种IO方式。
 
编译时：--enable-async-io=40 （我的是40，少了）
 
 
 
三：
 
helperOpenServers: Starting 5 'dnsserver' processes
ipcCreate: fork: (12) Cannot allocate memory
WARNING: Cannot run '/opt/squid/libexec/dnsserver' process.
 
系统内存被耗光，没有内存分配给squid的dns进程
 
 
 
四：
 
FATAL: xcalloc: Unable to allocate 1 blocks of 4108 bytes!
 
Squid 开启大内存导致进程内存溢出
 
 
 
五：
 
cache.log
2009/08/27 20:49:55| HTCP Disabled.
2009/08/27 20:49:55| sendto FD 17: (1) Operation not permitted
2009/08/27 20:49:55| ipcCreate: CHILD: hello write test failed
????
cu的朋友总结是configure时编译了--enable-icmp参数，去掉即可。
