用lvs_DR做负载,发现apache的error.log里,时不时会出现 request failed: error reading the headers

[Fri Jun 06 14:49:55 2008] [error] [client 121.15.89.193] request failed: error reading the headers
[Fri Jun 06 14:52:43 2008] [error] [client 118.78.184.117] request failed: error reading the headers
[Fri Jun 06 14:53:02 2008] [error] [client 220.163.27.244] request failed: error reading the headers

时不时的会出现这种错误,说是header头包有问题,不知道大家有没有遇到过这种情况.
