ATS 9.2.3 and proxy.config.http.per_server.connection.min

Hi

I'm upgrading from 7.1 to 9.2.3 and attempting to get a certain amount of connections kept open between ATS and upstream server to avoid connection creation overhead.

In 7.1 this worked well CONFIG proxy.config.http.origin_min_keep_alive_connections INT 50

In 9.2.3 enabling CONFIG proxy.config.http.per_server.connection.min INT 50 results in many lines of errors displayed in diags.log

[Oct 23 16:26:59.192] [ET_NET 0] ERROR: [http_ss] [188] number of connections should be greater than or equal to zero: 4294967295 [Oct 23 16:27:15.309] [ET_NET 0] ERROR: [http_ss] [210] number of connections should be greater than or equal to zero: 4294967295 [Oct 23 16:27:29.543] [ET_NET 1] ERROR: [http_ss] [203] number of connections should be greater than or equal to zero: 4294967295 [Oct 23 16:27:59.336] [ET_NET 0] ERROR: [http_ss] [219] number of connections should be greater than or equal to zero: 4294967295 [Oct 23 16:28:15.683] [ET_NET 0] ERROR: [http_ss] [241] number of connections should be greater than or equal to zero: 4294967295 [Oct 23 16:28:31.506] [ET_NET 1] ERROR: [http_ss] [234] number of connections should be greater than or equal to zero: 4294967295

Connections through proxy work even though those strange errors are displayed.

Might be worth noting that "CONFIG proxy.config.http.origin_min_keep_alive_connections INT 50" seems to have no effect other that producing those errors in log. It does not keep 50 connections open at origin server.

This still happens.
