Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 85 bytes)

PHP5中报Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 85 bytes)错误，对于memory_limit的设定已经从以往的8M扩大到128M的上限。对于配置中的定义解释是： memory_limit = 128M; Maximum amount of memory a script may consume (128MB) 最大单线程的独立内存
