Possibly, I've never heard of any gnutella program sharing much over 10,000 files. It's more likely a limitation of Java. If you want to 'try' to share that many files, add them to FW or LW bit by bit so they don't have to hash them all at once. So add 500 or 1,000 or less per occasion. Then add more later, bit by bit if possible. IMHO You might still have problems but it's the way I'd approach it. After all, it's the initial adding them to shares for the 1st time when they are hashed. AFAIK Something else you could do is, not try to connect to the network whilst you're adding the files/whilst the files are hashing. BTW unless I'm mistaken, I think I came across someone who was sharing 16 k files
