Hi,
I've started a project that make data analysis on thread dumps easier (at
least I hope so :) ).
An example of jupyter notebook:
https://github.com/ranophoenix/jvmthreadparser/blob/master/Thread%20Analysis.ipynb
All suggestions are welcomed.
Thanks,
Robert

Hi,
When a connection is closed by "ResetAbandoned" the invoke() method from
JdbcInterceptor is not called. Is it the expected behaviour?
-->server.xml

public class ExampleInterceptor extends JdbcInterceptor {

Ok
Do you have a firewall in between HTTPD & Tomcat? Is there anything that
could be breaking the connection?
No.
Best regards.

Hi,
Sometimes, in moments of high traffic for our patterns (170 req/sec), we
have a lot of threads like that:

Filip,
however, disabling the pool cleaner it should yield better results.
The documention[1] says:
"This value should not be set under 1 second"
Isn't true?

/decreases/ performance or the opposite (but it seems reasonable that
enforcing queue fairness would probably decrease performance).
The same problem happens with fairQueue=true. :(

Yes.
Thanks, Felix. We'll analyze this solution.
This behavior began in versions 6.0.41 and 7.0.54. Before that, everything
worked as expected.

Thanks, Daniel. But my question the question is why that was working in
6.0.39 and the firsts releases of 7.0.x?
Tomcat is not bind in java: anymore. Was it a feature request
or is it a bug?

Hi,
In a privileged context, a have the following jsp to test a global jndi
resource:
<%@ page session="false" import="java.util.*,java.sql.*,javax.naming.*,
javax.sql.*,org.apache.commons.dbcp.*" contentType="text/html" %>
<%!
protected void doLookup(JspWriter out) throws ServletException, IOE
ash occurs ("libnio.so") belongs to Java
Runtime, not Tomcat."
I know, but I decided to post here because the level of users is very good.
:)
Thanks,
Robert
