    good day!

    i have following system : RH 4.0 ES kernel 2.6.9-11 Intel SE7520JR2 board
    with latest network drivers.
    i am running application on SUN Java Application Server 8.1 .

    some specific workstations after some time working with www application (1/2 -
    1 hrs) freeze network connection to the port which they use to connect.
    netstat shows ESTABLISHED socket to that workstation and server never releases
    this socket, even if the workstation is rebooted. in this situation noone can
    connect to that port. browser shows 'Connected to server.com' and hangs on this
    message for ever and does not release it. other ports on SUN server continue to
    work, only the affected port is frozen. after i reboot SUN AS server, sockets
    are released and normal operation resumes.

    this happens from specific computers only so far. what can cause network socket
    to freeze? has anybody seen something similar on other systems? any
    suggestions? is it SUN AS problem or OS or network?

    thanks

    edmunds
