I am using Glassfish V1 b48? As far as I understand that is the most
recent build. I will have a look at the suggestion you made.
I am wondering if this issue has anything to do with the Java update
that happened recently on my machine 1.5.9->1.5.10
Since this update Glassfish has been all over the place and crashes the
machine regularly
Thanks very much
