[Planetlab-users] limit on number of connections to a port

[Neil Spring]

If by "connections" you mean TCP connections, then yes, your  
application can only have as many connections as file descriptors  
(sockets) allocated by the kernel.  (4,000-ish, I think, though  
people who have run into this limit are more likely to know).

I don't think you're giving enough precise information for a smarter  
answer.  Information like which system call fails with what errno  
value (perhaps from strace) would be helpful, but likely much more is  
required.
