I'll take a look ar Grinder, seems promising, thanks again.
Of course life is never easy :) now I have another problem... the
network admin configured 2 ofbiz instances having an apache in front of
them as balancer.. but apache "talks" with ofbiz instances via AJP
rather than mod_jk ..which seems to be a bottleneck..
Have you experienced that kind of things?

The Grinder is a nice tool for such things (and has a nice recording proxy).
BTW, make sure to set your HTTP and thread pool sizes adequately for the load
you are planning on.

Thanks everyone for the help!
Today we succeeded port to geronimo transaction 2.1 as well as the switch from
minerva to DBCP connection pool. It seems much better but I am not fully
content :)
Maybe because the automated testing tool I am using can not really hit hard
enough..
Any recommendation for such tools?
Of course upgrade to latest version was scheduled too but this would take
longer..

You're using a quite old version of OFBiz with the Minerva connection pool (I
can tell from the stack trace you sent earlier). The Minerva connection pool
has some issues with resetting connections when there are errors, especially if
there is any code that doesn't manage errors well, but also if there are
network layer issues or other sorts of things... it just doesn't recover at all.
You could try making changes to use the Apache DBCP connection pool that we use
now in OFBiz. To do so requires some low-level coding. You can look at the
current code base for hints, but there is still some work.
There are no known workarounds to this issue for really high volume sites, and
for low-medium volume sites the workaround was to restart the app server(s)
every day.

I was just asking myself if someone encountered before such problems on older
revisions..
Would be Geronimo ok to be used or shall I try something else?

I'm sorry the potential for problems with this approach is just too large for
me to be able to help you through it.

The attempt to update Ofbiz to recent revision is for the moment (time limits)
not possible.. there are so many differences... I am even not sure if bsh could
work further instead of the newly groovy ?! ....also the entity layer
handling.. etc
So what I tried was to back port the transaction management - latest attempt is attached
