Socket 24 is not connected any more (errno=-1)

[HANDE CANORUÇ]

I am using mod jk in order to connect tomcat and glassfish 3.1. In the
mod_jk log file I am getting these errors;

 [info]  ajp_send_request::jk_ajp_common.c (1178): Socket 24 is not
connected any more (errno=-1)
[info]  ajp_send_request::jk_ajp_common.c (1202): Error sending request.
Will try another pooled connection
 [info]  ajp_send_request::jk_ajp_common.c (1225): All endpoints are
disconnected or dead
 [info]  ajp_service::jk_ajp_common.c (1749): Sending request to tomcat
failed,  recoverable operation attempt=1



and in the server log file I am getting ;

SEVERE|glassfish3.1|org.apache.tomcat.util.threads.ThreadPool|_ThreadID=17;_ThreadName=Thread-1;|threadpool.busy|#]

Any suggestions??
