squid最多支持cache多少个object？

killua

有没有人研究过这个问题？目前我cache3000多万个object，出现squid进程自动重启了

具体的错误是

1. FATAL: xcalloc: Unable to allocate 1 blocks of 1048640 bytes!
   
2. 
   
3. Squid Cache (Version 2.6.STABLE20): Terminated abnormally.

我的存储方式是COSS

查了squid的FAQ，好像并不能解决我的问题

http://man.chinaunix.net/newsoft/squid/Squid_FAQ/FAQ-8.html#ss8.7 虽然有xmalloc: Unable to allocate的解释

Messages like "FATAL: xcalloc: Unable to allocate 4096 blocks of 1 bytes!" appear when Squid can't allocate more memory, and on most operating systems (inclusive BSD) there are only two possible reasons:

The machine is out of swap
The process' maximum data segment size has been reached



附上我的内存信息

1. # free
   
2.              total       used       free     shared    buffers     cached
   
3. Mem:       8161516    8119484      42032          0      82800    3760492
   
4. -/+ buffers/cache:    4276192    3885324
   
5. Swap:      2096472        208    2096264
