You could try to restart chassisd immediately (note the 'immediately'
keyword), which will kill and respawn the chassisd proccess at once.
This SHOULD be without traffic impact (did it a few times due to other
chassisd bug). But please remember that there is no guarantee that
this will be inpact-free. On the other hand 11.4R5 is pretty old so
you might be better off to upgrade to a new 11.4 release.
