Tried for some time now to duplicate the error without Java in the picture by
duplicating some of
the code patterns that get applied there in c++ and an ooRexx program.
However so far I was not able to recreate that crash.
The only thing that I can provoke (on a Windows box with 32-bit ooRexx) is a
condition indicating
that there are no more threads available from the system:

<--- standardConditionMsg(...), end.
"rii" stands for "Rexx interpreter instance", the condition occurs therefore at
Rexx intepreter
instance # 30,320 (sic!). The threads get excercised by Rexx code using reply
at two locations (one
location does a syssleep for random time after which the rii gets terminated).
In the case you may see utility in this particular scenario please let me know
and I submit a tidied
up version of the code (c++ plus an ooRexx program).

Short of new ideas, is there anything I could try to shed more light on this
problem while
excercising the Java server page test?
