    Hi Beesman,

    Sahi is being used on IE for a few years now by various organizations. So this bug has to be something very specific to your web application + Sahi or your configuration. Could you please give us more information?

    Hi,

    I have also observed a similar behavior while using the older(non-rhino) version. The behavior is expected as the test script was also loaded with every page load/refresh. So it consumes some memory but the consumption has hardly gone to alarming levels. Try to break down the script and run in a suite if the script size is too large. Also check if the script goes into deeply nested loops or even endless loops.

    Hi Beesman,

    We will look into this. Currently, does this affect your automation adversely?

    Hi,

    Use StackTrace utility to get a stack trace and try to figure out if there is any particular process/thread that is causing the memory problem. Try to see if something is causing an endless loop. You can get the utility at:
    http://www.adaptj.com/main/stacktrace
    Another thing you can try is get the latest JRE that is compatible with your IE.

    Hi Beesman,

    There was a bug and it has been fixed now.
    Would you like to get a build where you can check and let us know if it works?

    Hi Beesman,

    Thanks for the update.

    Could you specify when you get problem 1?

    I could not understand: " if there is a lot check of submit event"? Could you please explain that?

    Thanks,

    Nice work Beesman! Thanks a lot for your contributions! Your fix is right. It needed null checks in those two places.

    Thanks and regards,
