Problems with hosting a stable SRB2K server

[ulitimate]

I have recently been trying to host a SRB2K server for people to connect to via the master server but I have run into a couple of problems that have caused instability in running the server for more than a couple of hours at a time. For a while my server was having problems maintaining a connection to the master server for more than an hour before no longer being able to re-establish a connection. This would cause my server to be unlisted from the master server even though it was still up and running fine. I was able to fix this by using the BIRD Mod V2.1 (https://mb.srb2.org/showthread.php?t=45324) but now I'm dealing with a weird timeout bug. Initially, everyone is able to join the server just fine, but after a while everyone get's timed out when trying to join. I'm not sure if this is a time issue or a player count issue as I haven't been able to isolate those factors. There doesn't seem to be any in depth console information that I can access in order to debug the issue so I'm at a loss. I would like to be able to keep the server up for extended periods of time so people can join whenever but I don't have the time to constantly baby the server. If anyone knows a way of fixing these problems then I would really appreciate some help. My server is listed as "Ulitimate Server" on the master server casual page.
