Hi, I'll look. Getting the OT stuff to work after sleeping was difficult.
When the machines goes to sleep your sockets are all destroyed (Mind I've
noted in System 9.04 you now have the option of not having them destroyed.)
This makes life interesting when you awake since all those sockets are dead
you rely on Squeak cleaning up the issue from it's viewpoint, and of course
in the C code you've had to cleanup and track this issue, and debugging is
hard since code is run at sleep time which makes life difficult. However as
you point out it seems I've missed something.


PS Which OS, and version of OT do you use.

This is bad, but that is why you crash
