The maximum length of a disambiguation comment in the database is 255 characters. The release editor does not prevent people from entering strings longer than that. If it's an auto-edit, the release editor fails to submit the edit at all, causing an internal server error, if the edit is votable, it's entered into the queue but then ModBot fails to apply it and it causes an internal server error if someone tries to approve it.

The formhandler fields don't seem to have the same problem, they instead display an error like "Field should not exceed 255 characters. You entered 650".

The ISE from approving:
