similar issue - 3750e, only console works...telnet and SSH dead.  using local console
could see that all virtual consoles are stuck with a session still alive in them...
but those sessions dont exist and clearing them doesnt work. raised a case or 2 since
first seeing it..and each time have upgraded to latest IOS on a 'we believe its fixed'
promise. takes a while for the issue to appear and only seems to affect *some* switches
- remote access being lost is annoying...but not mission critical
