InstanceNotFoundException in re-deploying on 3.2.2

When I redeploy an application in jboss 3.2.2 (jetty and
tomcat) I have the attached exceptions (same for all
my ejbjars and wars).
At start time the deployment just go fine. It's when I
redeploy with copying my.ear in deploy directory that
things go bad. Whe I redeploy, undeploy seems to be ok
and then the exceptions starts on some modules (not
always the same), i did not notice in the log that
something went wrong before it breaks.
It breaks but it works :-), i.e my app just run fine with
the new deployed ear.
Anyway, don't know if it has a side effect but i use
commit option A on all my entity bean.

I've attached to this post two DEBUG server.log : one
with a normal start --> deployment is ok, and one with
the log starting with re-deployemnt of the same ear (ie
copy of the file in deploy) --> exceptions (line 2870 for
ex in attached file).
