seem's many threads are locked on this function: IceInternal::ObjectAdapterFactory::findObjectAdapter
why?

    Hi,

    It looks like you're using an old Ice version, we only provide free support on the forums for the latest Ice version. So I recommend to upgrade to 3.3.0 if you want us to help you with this matter. If you need commercial support for an older Ice version, please contact us at [email protected].

    Cheers,
    Benoit.

    can you sure it's the bug of ice-3.1.1?
  • benoitbenoit Rennes, FranceAdministrators, ZeroC Staff Benoit FoucherOrganization: ZeroC, Inc.Project: Ice ZeroC Staff
    Hi,

    I suspect it is but again I can't look into this some more unless you purchase commercial support for 3.1.1. I recommend to upgrade to 3.3.0 and see if this still occurs.

    Cheers,
    Benoit.

    this bug was never found before?
  • jerryluckyjerrylucky Member ruan shudongOrganization: HUSTProject: wap web site
    if this bug exists in Ice-3.3, why do i update to the version?
    i just want to known exactly what bug it's, and does it exist in Ice-3.3

    As Benoit said, we don't provide free support for earlier versions of Ice. If you want support for an earlier version of Ice, then please mail us at [email protected] to arrange for a support contract.
