I'm running ubuntu breezy badger on my t43 laptop and things have been going pretty well. I'm having some networking problems though. Sometimes when surfing and using the web, I can't connect to a server and on trying to ping it, I get the following

connect: no buffer space available

I've managed to isolate the problem occurence to instances when Azureus is running simultaneously. I thought it might be a problem of having too many open connections but restricting the maximum number of connections to 100-150 in azureus' settings doesn't help either. One possible reason could be that I'm using connecting from inside a vpn. I use the cisco vpn client.

Any suggestions to solve this problem would be great. I know that there have been some threads about this subject before, but I couldn't find any information about vpn clients or azureus.

Thanks
