Hello Mariano Norbert,
wouldn't the cheapest way be to just build a special case into
SqueakDBX error handling that could be activated via some option?
It's a recoverable error after all.
Same for OpenDBX, couldn't it just be an option? Me talking about
something I know nothing about.
And about supporting an extra built I'd say it's a pain that isn't
worth it. (Talking about something I know). So it can either be a
parameter in OpenDBX or it can be done in SqueakDBX.
As time permits I will try a port to see if I find more problems than
the recoverable connection error.
I will let you know.
Thanks
Herbert
