squid導致的硬碟只讀問題
各位大大，最近我的squid的伺服器很奇怪，老是出現內存溢出，Squid頻繁重啟，但是有時候重啟的時候，在cache_dir目錄重建完成以後出現了cache_dir目錄只讀問題，只能進行格式話，請各位老大幫忙看看啥問題啊？
系統centos5.4
squid:squid-2.6.STABLE22
swap:4G,內存也是4G，整個系統就跑一個squid，我的cache_mem 設置為3000M，大家再看下面的錯誤日誌：
FATAL: xcalloc: Unable to allocate 1 blocks of 4108 bytes!

請各位老大幫忙解決哈啊，被這個問題快搞死了～

先把cache_mem 改改看,據說這個超過物理內存三分之一不穩定...如果你是8G內存的話可以設置3000M
《解決方案》
chmod -R 777 /usr/local/squid/var/
還有緩存目錄創建允許當前用戶讀寫的最高許可權了嗎

這個我倒是想過，但是我其它的伺服器內存設置的也是一樣啊，但是其它的基本沒出過這個問題呢？

這個我倒沒給最高許可權，我的許可權是755，所有者給了squid的賬戶，應該也沒問題吧。

高手來啊，有遇到過這種問題的幫小弟提醒哈哪裡的問題啊～謝謝
