It could be its vty lines are exhausted.

This sometimes happens when an automated tool is logging in and not releasing the line upon job completion. If you can get in to console the commands "show lines" and "show users" may give you some indicators if my thought is the case.

Besides fixing the root cause, you can try adding a separate vty line with a low timeout set.
