BUG: Connecton problems

[pwalczysko]

Login to Howe as user-6, put on Group display, try to delete plates of all users, first deletion of 3-4 plates started, then went on and tried to delete some screens.
Possibly connected to recent work on Connection problems ?

Got

[pwalczysko]

Actually the error appears exactly when I try to expand the node of the next group after being done with deletions in the previous group.

[pwalczysko]

This situation might be connected to the fact that Howe ran out of space just now- but still

[jburel]

I have done some work, I will open a PR tomorrow. Nothing currently included in the build.

[jamoore]

This is definitely an issue of howe not having any more space, and there's nothing that could be done here other than throw the CannotCreateSessionException. If a different string in the reason field would have helped, Jean-marie, let me know.

[jburel]

The error is fine. Just was not handled. Added support as part of the connection work.
