  • Anyone else seeing a crash in WEDU with background scanning enabled?

  • Hi,

    This sounds like a WEDU bug. Unfortunately it is also one that is near impossible for us to re-produce without more information. By setting WATSON to request more detailed memory dumps etc… the next time it does happen in the field we can get more detailed information about the actual state of WEDU to help diagnose.

    I would recommend opening a support request with Customer Support Services in order to get dedicated resources working with you to reproduce the issue adn obtain more detailed memory dumps etc.
