Two other items to check:
1) Using session editing context in a background thread
2) Making an http request to a single threaded wo application during
the request response loop (e.g. An action tries to read an RSS feed
or HTML page from the same application using the same session
information)

Hello Chuck,
Attached a sample script we use to start our apps.
We store our logs in a file at location as specified this script. But
unfortunately, some times I feel/ see that some of the logs[again
unfortunately these unwritten logs turn out be Exception/Error
logs] are
not written in to these log files for some unknown reason. Any idea
why
how to fix this?
I tried below command to capture thread dump:
$ kill -3 <PID> >threaddump.txt
but I see nothing in this file. Is this the right way of capturing
thread
dumps? Please advise.
Thank You
Shravan

Hello Chuck,
We start our apps through scripts. We do not use Java Monitor/
wotaskd.
So, I did not work on editing SpawnOfWotaskd.sh
Please advise if this needs to be done and it makes sense for us.
Dude. You wrote the scripts. They are sending the stack trace
_somewhere_. Read your scripts.

Hello Chuck,
Thanks for your reply Chuck.
I have went through the link you have provided some time back and
tried
kill -3, but it is not outputting any ino, command is just
quitting
quietly.
Did you follow all of the stuff on that page? Editing
SpawnOfWotaskd.sh?
Can you advise what sort of things I need to check in my app,
which
may
cause these issues, such that we can have a resolution asap. I
mean
any
code blocks/ design/ ?
Generally throwing exceptions from awake(), sleep(), and
terminate()
or mishandling editing context locking are common problems. There
should be some deadlock information in the wiki.

Hello Aurelien,
Yep, we upgraded to 5.2.1 - 5.2.2 - 5.2.3 - 5.2.4.
We do sometimes see broken pipe exception in our logs, I heard
that
this
generally happens when the connection between woadptor and
browser
is idle
for certain amount of time, whcih generally means the connection
between
woadaptor and browser is broken. Am I right?
How can we find dead locks in our application?
http://www.gvcsitemaker.com/gvc.webobjects/
faq&mode=single&recordID=41413
Please advise a solution as to how to determine which part of
the
application is causing this problem.
You need to analyze the thread dumps, then look in your code to
see
what could be causing that. It can be difficult.

Hi,
We have been battered by CLOSE_WAIT processes and instances
hang.
We are running our application on Solaris 5.8 boxes with
WebObjects
5.2.4, Java 1.4.2_17.
The 5.2 updates are "cumulative", do you apply 5.2.3 update ?
(and
5.2.1
5.2.2)
it fix a bug about close_wait (
http://docs.info.apple.com/article.html?artnum=107873 )
We have collected some process dumps and consulted Sun, they
analyzed
and blame our code, alas!!!
We see CLOSE_WAIT state of a process for both java and httpd
processes.
Is the java process is your app or the wotaskd ?
If it is your app, is it the only application that has the
problem ?
We see degradation in our application performance as the day
progresses and our app becomes unresponsive various times, we
restart
the app various times during day.
Don't you have java exception: broken pipe in your application
logs ?
Could any one please advise us a solution to find the
reason for
instance hang or fix CLOSE_WAIT processes generation.
You may also look for deadlocks in your apps.
Regards
Aurelien
