Hi,
As the error message hints, a common cause for this exception is the
client closing the browser while you're generating the page. People do
that often when they run into error pages, e.g. as soon as they see the
404 header. I don't know what the rest of your 404.jsp does, but you
should try

Hola,
I did a thread dump (SIG-QUIT) on both the JRun and Tomcat environments
during the refresh button load test and the differences are
significant.
The differences in internal thread management between any two servers
are likely to be significant.
Tomcat: Java CPU% exceeds 80%. Site
In my case, tomcat does not recover.
but what I would like to get answered are the questions about the behavior
of tomcat in my mail. I think it doesn't matter if it gets crashed or
not, it's just the fact that a processors stays processing a job after
apache allready dropped it's own thread
I was literally about to post on the same subject. If anyone knows how
Tomcat (and in my case Apache 2.0.48+mod_jk2 on Solaris 8) handles
interrupted/broken connections this would be helpful.
Just to add my own observations... I can push over our test
environment simply by hitting refresh
Just to add some PART 3...
it might be usefull to have the mod_jk connector give a clear message
other than 404 to the browser, wouldn't it ? (of course we can setup a
custom 404, but it's not the same as a real 404 !)

processor usage is indeed eating whole cpu, but machine doesn't die at

Howdy,
This is not related to your DB (at least, not likely to be related to
your DB). It's probably your user closing the browser while the request
is still processing. This issue in Coyote was fixed in Tomcat 4.1.24 I
believe, so you should try upgrading to tomcat 4.1.29 or 5.0.16 and see

Yup, that's a good theory. Have you experimented with the connectionTimeout

The applet might be buggy and close the connection before the entire response

Hi,
I don't think the connectionTimeout is the problem. I tought more about
corrupted connection than a lost connection, because the applet is made
by more internal frames. This special frame will be closed after this
error, but applet continues to work!

A broken pipe is usually caused by someone clicking on a link and then when
nothing happens clicking on a different link. So the first click is
probably to a slow page (maybe due to a long db query etc). Tomcat will
At the moment, mod_jk(12) drops the connection to Tomcat if the client
drops the connection (e.g. hits the stop button) before the page is fully
sent. I won't bore people with the details of why it works this way, but
you can usually ignore it.

In my experience those broken pipe errors seem to happen most often when

was directly connecting to tomcat, not when I'm using apache as a front

Hi,
If your servlets or JSP pages have any problems and you see
java.lang.OutOfMemoryError in your log files or in a stack trace
generated by the Java Virtual Machine (JVM), then you probably need to
increase the JVM's maximum heap size.
Solaris 1.2 and 1.3 JVMs have a default maximum heap size
On a windows machine where apache is starting tomcat, where would I place the switch?
I placed it as part of CATALINA_OPS by entering
set CATALINA_OPTS=-Xms256m -Xmx512m
near the beginning of the catalina.bat startup file. Not sure if this was where to
place it or not though.

Hi Markus,
This is a problem has been puzzling me for quite
a while too.
However, it does seem related to an exception being

some jsp I have written throws an exception (which
