Then probably the answer is no.

That's actually limiting VLV requests. You didn't ask about VLV requests, you
asked about sort requests. Ask the wrong question, get a useless answer. So
now, what does draft-ietf-ldapv3-vlv say?
I guess this is a relevant section (the only occurrences of "connection"
in the spec):
"contextID values have no validity outside
the connection and query with which they were received. A client MUST
NOT submit a contextID which it received from a different connection,
a different query, or a different server."
which does partly answer my question about the VLV request, but says nothing about any
related sort operation.

I see no such error here. I can run ldapsearch and send VLV requests ad
nauseam. Most likely you have misconfigured something again.
Always possible, but I would expect that ldapsearch terminating would cause the server to
drop the connection and clean up any sort request associated with a vlv request on that
connection. I'll do some more investigation.
