Hi,
If you have freezes, show them in your log-file incl. description of the channel.
I think, Moderator is not stupid to set this value as general for all packages, not only for SkyUK.
Freezes may occur if your Internet provider uses dynamic IP addresses, you may check it. Static IP is better.
Advice - leave only one (main) server, disable the 2nd one (reserve) and check if freezes will continue or stop.
How to check- enter billing, Connections history and check if you are connected from different IP addresses. If so, delete the 2nd server (reserve) and leave only main server.
