I am trying to migrate an older site from:
RedHat 7.2, JRE 1.4.1, Tomcat 4.1.24, Apache 1.3
to
RHEL 3, JRE 1.4.2, Tomcat 4.1.24, Apache 2.0, mod_jk 1.2.5
and I'm seeing something strange. I am seeing pauses in page rendering that
are unrelated to GC. They are pretty much exactly (60 seconds + render time)
in length.
I've tried http and http.worker. I've tried setting LD_ASSUME_KERNEL to turn
off the new threading model. I'm still seeing this. Looking through the
archives it looks like some people have seen this and that is has something
to do with mod_jk/tomcat communications, but there does not appear to be a
resolution.
I've happy to provide copies of config files and such as well as entertain
suggestions for things to try.
Here is the relevant snippit of my server.xml file:
<!-- Define a Coyote/JK2 AJP 1.3 Connector on port 8009 -->
<Connector className="org.apache.coyote.tomcat4.CoyoteConnector"
port="8009" minProcessors="5" maxProcessors="900"
maxThreads="900"
enableLookups="false" redirectPort="8443"
acceptCount="10" debug="0" connectionTimeout="0"
useURIValidationHack="false"
protocolHandlerClassName="org.apache.jk.server.JkCoyoteHandler"/>
Thanks,
Allen
