client sent too short userid cookie

[alexberg]

Hi

I'm getting a lot of "client sent too short userid cookie" errors in
error.log. What I see is the following:

client sent too short userid cookie "odsp=;  odsp=rB4An1Xcv3sLIBgDBjypAg=="

And, of course, the uid module resets the cookie (even though it can be
recovered) and I end up not seeing same users. In other words, I have a
$uid_set variable, and no $uid_got (but if I try to read cookie with Lua, I
can successfully read odsp).

Is there a way to somehow prevent this or recover from this?
