thanks for your reply.

I have abserved squid logs at that time.
When this happened, the response time of squid is often more than 30 seconds,
and no other urls are abnormal.

I suspect that cache of "http://xxx.com.cn/public/js/livecast/function.js" has
problem, and maybe it's a bug of squid.

I didnot use disk as cache, but mem:
cache_mem 1800 MB
cache_dir null /data1/squid/var/cache

and I often find abnormal output of squidclient:
Memory usage for squid via mallinfo():
        Total space in arena: -1980532 KB
        Ordinary blocks: -1987251 KB 50184 blks
        Small blocks: 0 KB 0 blks
        Holding blocks: 8840 KB 2 blks

        Total in use: -1978411 KB 100%
        Total free: 6718 KB 0%
        Total size: -1971692 KB
here, memory size always is negative value? int overflow?

and

$squidclient -p 80 mgr:5min
sample_start_time = 1228439560.788657 (Fri, 05 Dec 2008 01:12:40 GMT)
sample_end_time = 1228444076.391143 (Fri, 05 Dec 2008 02:27:56 GMT)
here, sample time is wrong.
