When using the sssvlv overlay how does the client tell the server that the

sssvlv-max or sssvlv-maxpercon are exceeded?

There is no official mechanism for this. This is a flaw in the Sorting/VLV specification. For Paged Results you simply send a followup request with pagesize set to zero, but that doesn't apply for VLV.

I believe in our current implementation, if you send a new Paged Results request on a connection that has VLVs outstanding, one of the VLVs will be aborted. Unfortunately, if you have multiple VLVs outstanding, there's no way to determine which one gets aborted. (Apparently this was overlooked when patching the overlay to allow multiple VLVs on a connection...)
