When it stops working could you try eval'ing (slime-busy-p) ?

The `slime-space' command won't do arglist lookup if it thinks we're
busy, i.e. that we have unanswered RPC(s) to Lisp. Particularly with
threads though it could be possible for a request to get stuck or to
somehow die without sending a reply, in which case Emacs could get
stuck thinking that it's busy.

So if (slime-busy-p) is true then it's probably stuck, and you can use
`M-x slime-reset' to safely cancel any unanswered RPCs and continue.
If (slime-busy-p) is false then it must be something else..
