Bad data exception and high CPU usage

[SandeepKarumuri1]

we are seeing bad data exception and also high CPU usage (reaching 100% and not coming down) in the event logs, below are the Application error and .net error, no installations was done, no upgrades or anything. Any thoughts or suggestions would be appreciated.

This looks like a QlikSense question so I will move the Question to the Sense board.

The windows event logs for .net is not telling us very much. You have to start looking in the QlikSense logs.

Is there an issue for end users?

Can you check which process is using the CPU?

@Maria_Halley  - Thanks for directing to right location.

I don't think there is a issue for end users but the monitoring system is generating alerts.

we have to check QlikSense service logs?, we will check which process is taking the CPU

We are having a similar problem also. Having to reboot every few days to eliminate 100% CPU load.
