Using Shark in the CHUD tools can prove very helpful in trying to track down where bottle necks are and how to improve performance.

Thank you all very much for your help.

At least now I know it's my application trying to respond to the
WOAdapter after the adapter has marked that direct action dead. I will
now try refactoring the code to make it quicker and I'll probably try
and figure out how to bump up the direct action time till death
setting as well.

Again, thanks for everything.

100 TPM shouldn't be an issue with 5.3.1

One of the times it occurs is when the server is too slow in
responding. On a development system this can be due to exceeding
100 TPM, which stalls. Look for such a message in the run log.

I'm seeing the following error repeatedly in the logs and I have no
idea what it is.

Here are a few examples of what shows in the logs:

Exception while sending response: java.net.SocketException: Broken

There is no information in the exception that even tells me where to
find the problem.


Little information so you know where this is coming from.

XServe
Mac OS X 10.4.3 Server
Web Objects 5.3.1
Connects to separate XServe running OpenBase 9.1

Now the application is entirely composed of direct actions. It's
something of a web service but it doesn't use SOAP or anything like
that. It just gets requests via direct actions and returns HTML data.


If the exception had a class listed or line number of something I
could tell you more. But it have no idea what part of the application
is generating this error.


Thanks for any help you might be able to provide.
