今早pw和dz平台同时报错

问题一：DZ平台错误偶尔打开页面出现404 进入系统后台发现有一个php 进程 100%

跟踪一下发现如下错误：

unlink(“data/threadcache/d/6/5/”) = -1 ENOENT (No such file or directory)

stat(“data/threadcache/d/6/5/”, 0x7fff092e9750) = -1 ENOENT (No such file or directory)

解决：估计是更新缓存造成的，重启哈php服务就可解决。

问题二：PW系统崩溃了。

错误：Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 8329487 bytes)

怎么内存占用那么多。。。

解决办法：把 php.ini 里的memory_limit = 128M 改为 memory_limit = 256M ，方可解决，具体 什么程序造成的，暂时木时间查找，先用着吧！
