Hard to say what's up. There have been some changes in tramp-cleanup-*
functions, which might improve the behavior. Do you have a chance to
upgrade to Tramp 2.5.3.1 from GNU ELPA?

If this still happens, pls set tramp-verbose to 6 and
tramp-debug-to-file to t. The former variable triggers Tramp to write
debug messages, and the latter one (new in Tramp 2.5) initiates to write
these debug messages to file in parallel. Good for post-mortem analysis.

Please check the Tramp messages on file whether you see something which
tells you what's up. If you don't find something, please show the file here.

No, these values are active only if a connection is active. The
existence of these values does not mean that a connection is initiated.
