There are two 'while' loops in cLircRemote::Action(), but both
check Running(), so I would expect them to end properly.

You could try adding something like

   dsyslog("%d", __LINE__);

at a few places in cLircRemote::Action() to find out where
exactly it is hanging, as in

   while (Running() && f >= 0) {

         dsyslog("%d", __LINE__);
         bool ready = cFile::FileReady(f, timeout);
         dsyslog("%d", __LINE__);
         int ret = ready ? safe_read(f, buf, sizeof(buf)) : -1;
         dsyslog("%d", __LINE__);

         if (ready && ret <= 0 ) {

etc.
