It was a small piece of the config, and nothing from the SQL table.

As soon as i add a VR server to the config with just the most basic setup i can think of then requests starts getting rejected.
Do you have a patch from the default config, so I can test it?

The SQL module has "readdlients = yes". The virtual server doesn't have that.
If the same module is used in multiple virtual servers, then the module is only initialized once. So there's no way it can read the NAS table multiple times.
So I don't know what you mean by "they all use same NAS table".
The debug log you posted shows that the NAS table lists clients, and has a defined virtual server. You only posted a small piece of the debug output (again, NOT recommended), so it's impossible to tell what's going on.

I have no idea what that means. A virtual server doesn't use a NAS table. An SQL module uses a NAS table.

I think you're not clear on what the server does.
a) clients are read by the SQL module, not by a virtual server
b) each SQL module is initialized once, and reads the NAS table once
c) an SQL module can be used in multiple virtual servers
d) if the virtual servers don't have a "listen" section, the clients read from the NAS table become global clients
I *think* what you've done is configured multiple SQL modules, and then set "read_clients = yes" for all of them, and pointed all of them to the same NAS table. That doesn't make any sense. Don't do that. Be sure that the clients are read ONCE, so that there are no duplicates.
And post the FULL debug log from v3. The tiny pieces you've posted mean it's impossible to tell exactly what's going on. That makes it MUCH harder to help you.
