tODE can't debug and restart errors that happened in other gems that are on
the object log.  See this issue: 

https://github.com/dalehenrich/tode/issues/39

You can inspect the stack though.



I sometimes use GemTools on the remote server and use ssh -X forwarding to
get the GUI.  Its faster than local GemTools + remote GemStone because only
the X11 stuff is sent over the wire.  See here:

Its tolerable for sure.
