Sounds like system (C) has an idle timeout configured and system (B) doesn't.
The obvious test is to see what happens if, after telnet to (B), you telnet from
there to (C) and leave it idle - does that time out as well?
This problem could be attributed to any number of causes - network problems,
idle timeouts, etc. I haven't ever seen this problem myself, so I think it's
safe to call it a fluke.
