Subject please explain errors in catalina.out and mod_kj's log
Date Tue, 25 Feb 2003 15:20:55 GMT
hi,

many people seem to have the follwing lines in their catalina.out:

25.02.2003 16:07:31 org.apache.jk.common.ChannelSocket processConnection
INFO: server has been restarted or reset this connection
25.02.2003 16:07:33 org.apache.jk.common.ChannelSocket processConnection
INFO: connection timeout reached

i now set mod_jk's log-level to "error", and now i have those lines in 
mod_jk's log:
   see below

i checked my tomcat-configuration. the timeout is at it's maximum 
(60sec) although i haven't tried using -1 yet.
i wouldn't like a timeout of -1 (hopefully meaning INFINITY) because a 
dead connection would never be detected!

i guess, tomcat is killing the connections (because of timeout) and 
mod_jk has to establish a new connection.

mod_jk doesn't have something like a keep-alive option, so what am i 
supposed to do!?


a snippet from my mod_jk.log:
