When listening on 0.0.0.0, that means that you are listening on all 
available TCP/IP addresses, and in this case port 8009.  So yes, it is 
normal.

RE: Is this normal for Tomcat?

[Angelov, Rossen]

I'm not sure if I understand the question very well but the original
HttpServletResponse is being passed to the constructor of another class to
create an instance and then this instance is changed in the course of the
execution.

At the end it's printed out through PrintWriter and then flushed.

This could be a thread safety issue. 

Are you using a servlet that has instance variables to generate the

RE: Is this normal for Tomcat?

[Angelov, Rossen]

Well, I gave you wrong information. The line with categoryFactory is not
being used. That was the old configuration.

All I have in the code is org.apache.log4j.Logger.getLogger and
PropertyConfigurator.configure(log4jfile), there is no categoryFactory
involved.

It's not only the cookies but the whole response. 

Is there some kind of server caching that Tomcat might be doing?

I have disabled caching on HTTP level:
response.setHeader("pragma", "no-cache");
response.setHeader("Cache-Control", "no-cache");
response.setDateHeader("Expires", 0);

Sorry, I meant, I'm not using Apache's FileLogger to log this data.

Both are using FileAppender with different log4j.appender.LOG.File property.

The categoryFactory, rootCategory, PatternLayout and ConversionPattern are
the same.

RE: Is this normal for Tomcat?

[Angelov, Rossen]

No, they are completely different:

webapps -> context1 -> WEB-INF -> classes -> com/context1 
webapps -> context2 -> WEB-INF -> classes -> com/context2 

I don't have anything in common/lib or common/classes used by these
servlets.
log4j has two different paths for the log files. I'm not using FileAppender,
the servlets read in the log4j properties from a separate configuration
files passed as  when the servlet starts.

Howdy,
Do you have any code in the common/lib or common/classes repository that
these two contexts share?  Is the File destination for log4j's
FileAppender configured to be the same for the two contexts?

RE: is this normal??

[Ben Ricker]

I found a trick that might help: up your sar reports to take a snapshot
every minute. Then, when you notice the CPU pegging, go through the sar
reports for CPU usage and try to find the minute that they start. Then,
you can go back through the Apache access logs (mod_jk.log perhaps),
etc. to see if you can correlate a specific request with the the
problem.

Good Luck,

RE: is this normal??

[Randy Paries]

I am running 

jakarta-tomcat-4.0.4  jdk1.3.1_04 apache-1.3.27-2 

I have enabled server stats (thanks Jan)

I stop and started and it is back to normal. So when this does this
again, I will see if the server status helps

Thanks for all the suggestions

Randy

Are you using tomcat 3.x by any chance?  We had a CPU problem with 3.2.4
that we could never resolve.  The problem went away with our recent

Re: RE: is this normal??

[jmong]

I have to concur with the following observation.

Try to check what the apache processes are doing. If you've enabled 
server-status on your box and have installed GET (as part of the perl 
LWP) grep for the pid

GET /server-status | grep 

or access it http:///server-status

On older tomcat versions (i.e. 3.2.1), it would seem that older 
clients (i.e. HTTP/1.0) would hang up on the POST part

ie.

POST /path/to/form/process.jsp HTTP/1.0

Typically my only recourse is to kill the offending process and/or 
restart tomcat and apache.

kill -9 

Hope that helps

RE: is this normal??

[Ben Ricker]

There is probably a problem going on there. I find it strange that you
have so much cumulative CPU time on the httpd processes. To me, they
look hung (in so far as I can tell). Since most apps are transactional
in nature (i.e., individual requests being fulfilled rather quickly),
you would expect to see the Apache processes using CPU, then giving it
up rather quickly. Of course, other httpd processes will also pop in and
out of CPU usage as individual requests pop in.

How long has this Apache/Tomcat been running? You might try a restart of
both and see if the same behavior comes right back or if it takes time.
You may have an issue in the app which is triggering a hang.

Of course, on a "pretty busy web server", you may get such cumulative
times, but you should still see httpd processes popping in and out of
CPU usage as they handle their respective requests. If the same PIDs sit
there pegging the CPU incessently, you most likely have an issue.

HTH,

Ben Ricker
