    Hello,

    We have discovered an issue with the Wyse clients (V10L and C10L) when helpdesk attempt to shadow a session.

    Users are running Citrix published desktop on a XenApp 5.0 server. Session settings are 1920×1080 resolution, 16 bit colour. They are using 22″ wide screens.

    When a helpdesk staff attempts to shadow a session the published desktop on the users machine disconnects and one of two errors are displayed on the screen:

    Trap: Protection fault, EIP = 0x1121ba
    (Press power button to restart)

    or

    ICA (Published desktop: Not enough space
    and in the system event log is:
    mfail (ICA): out of memory 951517184 errno =11

    With the trap fault error, you need to power cycle the thin client. Sometimes even remove power and reconnect in order for the device to work again.

    With the not enough space error you can log back an return to your disconnected session.

    We have performed some testing and it appears to be related to the size of the session and the amount of memory it is using. For instance if we change to a 17″ monitor shadowing works fine.

    I’m going to log a call with Wyse Support but just wondering if anyone else has experienced this.
    And yes we are running the latest firmware 6.5.0_34

    Thanks.

    Some further testing has led to the discovery that this is happening on WinXP PC’s also. So this is a Citrix issue.

    We are now experiencing the same problem.
    Did anyone have a resolution or workaround for this?

    Hi, Wyse provided me with a demo firmware which appears to have resolved the issue with shadowing however we are getting a number of session disconnects with this firmware so it’s not ideal.
