Subject problems with apache-tomcat connection ...
Date Thu, 28 Oct 2004 13:12:17 GMT

Hi everybody, sorry if this is a silly question because I am  not an 
expert, but I was looking for the solution to my problem consulting to 
google and nobody has answered about the following problems with 
apache-tomcat connection:

a) I have Solaris 8, apache 2.0.47, jdk 1.4.2, tomcat 4.1.24 and the 
binary module of mod_jk version 2-2.0.42
b) Seems that the system works ok, however I got the following messages in 
the apache error_log file:

[error] Error ajp_process_callback - write failed
[error] ajp13.service() ajpGetReply recoverable error 3
Error ajp_process_callback - write failed
ajp13.service() ajpGetReply recoverable 
error 3
ajp13.service() Error  forwarding ajp13:localhost:8009 1 0
[error] mod_jk.handler() Error connecting to tomcat 3

scoreboard
[Thu Oct 28 08:02:31 2004] [error] mod_jk child init 1 -2

and in the tomcat logs file:

...

My question is, what is missing in my configuration ?. How these problems 
affect the performance of my system ?.

Thanks a lot,
