Re: memory leak ?

Hi Michael,

Thanks again for the explanation, I am starting to understand CORBA by
now. I was away at an important meeting (MIPTEC, Basel, Switzerland)
last week in which we demonstrated our new software with CORBA and
everything went fine, thanks yo you all for helping me out in the
previous weeks ! Free software support is great and it works !

I am curious if other people have also used CORBA for automation ? We
now implement every driver for a device with its own CORBA-server and
interconnect them all, everything runs stable. One of the biggest
adavantages is that a problem in the client did not bring down the
server and normal operation continued after reconnecting another client
to the server.

Best regards,

Peter Van Osta
