Do you mean these messages ?  

With "use kqueue"
2007/04/26 22:26:15 [info] 4133#0: *3048 kevent() reported that client
192.168.0.100 closed keepalive connection

With "use poll"
2007/04/26 22:59:48 [info] 10189#0: *375 client 192.168.0.100 closed
keepalive connection

They are not actually errors, they are the info messages and this is normal.
If client is MSIE you will see

"... [info] ... client ... closed keepalive connection (54: Connection
reset by peer)"

It's also normal: MSIE always closes keep-alive connection with RST packet.
