Hello people,
I really can not explain this. We are stress testing a server. We use the following configuration: the server runs on a FreeBSD box (or Linux, with a similar effect). A multithreaded tester program runs on a Win2K box and emulates random multiuser activity. The FreeBSD box stops responding to network requests every 20-30 minutes. I can't even connect to its FTP server. If I don't touch it, it does not "unstuck" for quite a while. But, if I do something with it, like start a Web browser on it and access the server, or just do netstat, it became active again shortly. Can anyone explain this? Is it some form of protection from denial of service attack? The tester program generates a lot of requests, and does it very fast, so, it does look like an attack. We do use SO_REUSEADDR option on the server sockets, so, this is covered. Any ideas? Any recommendations? I would really appreciate some help. We don't have any other problems with this server so far, but this one. Thanks in advance, Arkadi.
