Hi,
I'm having a problem with Apache,Tomcat, and mod_jk.
Apache - 1.3.33
Tomcat - 5.5.12
mod_jk - 1.2.20
We have a jsp web page which calls a servlet to load images. The servlet
gets the image by connecting to a java application running on a seperate
file server. Every now and then we get the error at the end of this email.
Using some stats from the this morning, the jsp page was called 263
times and the servlet 490 times in 38 minutes. Out of the 490 times the
servlet was called, 10 of those generated errors. We have been unable to
reproduce this error on our test & dev systems. On our dev and test
systems, we were able to call the jsp page 184 times and the servlet 500
times in a little over a minute and did not get any errors. Everything
had been working fine on our old production server for 2+ years which
used the same apache version but Tomcat 3.2.3 and JDK1.2.2 . The old
production system also used the AJP12 connection protocol where the new
system uses the AJP 1.3 connection protocol.
Here's some info from the conf files. All load balancing stuff in
workers.properties is commented out.
Thanks !
walt
