I`m using Tomcat 5.0.30 / Apache 2.0.54 / JK 1.2.14.1
I looked a bit in the source of the Tomcat JK connector,
and the 'connectionTimeout' parameter of the is
relayed to 'soTimeout' of the listening JK sockets "ChannelSocket.java".
...which takes us to the java.net.Socket api and SO_TIMEOUT parameter.
Seems to me that mod_jk in Apache keeps the connection opened,
therefore never closing it and reusing it for future calls.
If so, and if I set a connectionTimeout on the Tomcat JK connector, it would
always close the connection with a TimeoutException. That would
explain the log entries.
I don't know, I'm just guessing because my system is not in production
yet, but if I set my Tomcat connector to 'no timeout' and my Apache
worker to socket_timeout=30 secs, wouldn't the sockets be recycled on both
ends
anyway when not active for 30 secs?
My Apache workers.properties looks like:
worker.tomcat1.port=8009
worker.tomcat1.host=localhost
worker.tomcat1.type=ajp13
worker.tomcat1.cachesize=150
worker.tomcat1.cache_timeout=600
worker.tomcat1.recycle_timeout=300
worker.tomcat1.socket_timeout=30
worker.tomcat1.socket_keepalive=1
and I haven't had the log entry in Tomcat since I set the
cache and timeouts in Apache.
Hope it helps...
