Thank you for your input.
I have read some of it and I can only agree with you,
but now my problem seems to be that SUN ONE WEB Server,
doesnt call servlet.destroy() - it just kills the process
'kill -9'...
And I have posted that question [does SUN ONE call destroy()?] more
than once - no answer.
Thanks SUN for keeping the light shine on Java development. :-(
