On the last friday of every month the BES router generates event id 10000 and no one can send or receive email. I am running BES 4.1.3.16 on Exchange 2003 SP1 server. Once I reboot the server, all is well.

If a third party app began using port 4101, would it shut down the Blackberry Router service, or would it continue to run but generate event id 10000 yet prevent mail transfer?

Thank you.

Why would you be using port 4101 for another application? Doesn't the app have it's own network communication (port & protocol) channel? This would present a conflict that will affect mail redirection.

this is what I am trying to figure out. what, if anything, might be using that port on the last Friday of the month.

The "-o" option of netstat will show you the PIDs that own open connections. When you get the error, stop the router then do "netstat -ona" to see if anything's using the port.
