nginx0.8.8 purge_cache module 中出现...is too small...

nginx 重启之后 用purge 会出现以上错误
nginx log ：
2009/11/17 15:03:52 [crit] 1553#0: *1 cache file "/data/nginx_cache/etwebservice/a/2b/b3a2527b6f3a38d63663ee436e7d82ba" is too small, client: 222.66.142.229, server: localhost, request: "HEAD /purge/RestTakeoutServer/dish/B10I24R57547/list?commentCount=5 HTTP/1.1", host: "222.66.142.229"

客户端请求出错

Server: nginx/0.8.24

解决办法是更新patch到nginx0.8.26
