I have several SGE2000 in production and every night I save the current configuration to a tftf server... from time to time I get the following error:
20-Oct-2010 11:29:00 %TFTP-C-OPEN: No free UDP port
20-Oct-2010 11:29:00 %COPY-W-TRAP: The copy operation has failed
Copy: Can't open TFTP client
At this time, the only way to be able to save the config again is rebooting the switch, but this is not a solution I am comfort.... Someone knows why this is happening and how to solve it without rebotting the switch?.
In at least one of these cases, a firmware upgrade was released to solve this issue, though it's impossible to tell if these are related or not. At any rate, this issue requires attention. Is there a way to contact Cisco and report a bug?
As an example, lets say you do netstat -a on your computer. There are services that associate to ports. These services could be using your TFTP resources. So, you should find out what devices or services are using these ports.

I don't have any other services using ports on my TFTP server. In fact, I only start up the TFTP server just before I do the copy operation. Further, I have another TFTP operation on a different switch that succeeds immediately after this one fails.
I'm confident the problem is not on my TFTP server (or the machine hosting the server) as no other devices have problems accessing it.
