Weblogic Assertion Error

[Tige Kala]

Hello,
I have run into the following problem. When running a very long lasting
bean transaction on one BEA Weblogic 6.1 SP2 application server I get no errors,
but on the other one that in fact should be quite similar to the first one, I get:

EJB Exception: ; nested exception is:
weblogic.utils.AssertionError: ***** ASSERTION FAILED *****[ attempt to pop from an empty stack ] ...

The exception is raised from my EJB-s ejbPassivate() method, that only does the following:

public void ejbPassivate() {
logger = null;
monitorLogger = null;
try {
ctx.close();
} catch (Exception e) {
e.printStackTrace();
}
}

"ctx" represents a UserTransaction.
What I am doing is calculating some dividends, and this takes time. There I
have several thousand holders, and in a for loop, I calculate dividends for each one of them. The application doing this represents a stateful session bean (EJB).
I have done research, consulted with developers by my side, but still get this strange error.
What causes this? What should I check? Is it in Weblogic application server's configuration or in the java bean?
Thanks in advace!

We commented out the ctx.close() in the ejbPassivate()
method, as it is there only for cosmetic purposes. So we
now leave the transient context to be removed by the
JVM Carbage Collector.

Are u saying when u remove the ctx.close(), everything works fine?
Assertion error is very common in weblogic. My suggestion to you will be to check in the webogic managed/admin server logs, your managed server startup logs to find out if you get any stacktrace. Also check inside the ejbs to make sure u are printing the original stack trace.
Can't help much but if you provide stacktrace it will be of some help.
