QVIIS Webserver failed randomly

Hi all,

Our qlikview IIS webserver occasionally fails. At first I thought it was due to some system issues. But it seems to be a recurring application problem.

Every other month, the server just stops working . Restarting all Qlikview services fix it and bring the server back online. But has any one see this issue and have any clue of what is going on here? Below is the error i got from the log at QlikTech directory which I have no idea what it means.

Any idea would help. Thanks a bunch.
