'Current Open Cursors Count' alert in EM

I'm using 11.1.0.7 I've been getting above alert in EM. In details the message says. (Metrics "Current Open Cursors Count" is at 1251). The warning Threshold   is 1200. I've read ID 787830.1 which points as a solution to increase the warning Threshold.

Is that the solution? Can someone explain to me or point me to a documentation that explains what would be the consequences of having more than 1200 Open Cursors and why the limit is set there?

Thanks
