I did some testing: it's not related to X anyway. tcpdump I tried and will examine the results. The server is a slower machine, laptop Pentium 166 MHz, the clients I tried are faster, Pentium 400 and Pentium 1900 MHz. So far I guess the server is flooded. During the freeze, the server keeps getting flooded with packets from the client, as I can see on the router. Thanks for giving the tip of using tcpdump! And I will do memory-testing, but I don't suspect the server to have bad memory. I use the server daily without problems. Thanks for advice!
