NIS 2011's background tasks resulting in constant disk activity

Hi,

 

I've recently become seriously annoyed at the background tasks NIS 2011 is performing. This is resulting in excessive disk activity which can last up to six hours (and I had to interrupt that to get it to stop). I don't think this has anything to do with idle scans as the logs indicate they only take a few minutes. Also, my full system scans only take three hours, so I really want to know what NIS is doing to my system and if there's any way I can prevent it from happening again.

 

The constant disk activity (and therefore, noise) can be heard downstairs and is actually problematic when it comes to sleep.

 

Otherwise, I like this product. But it's getting to the point where I'm thinking about uninstalling due to the constant noise.

 

Suggestions/insights would be greatly appreciated.

 

Thanks,

Jen
