It is rebooting frequently in the sense, what's the interval of reboot, is it minutes/hours/days. ??

Can you attach the logs for this ??

Just see whether memory leak bug is there for this IOS ?

Monitor the memory consumption at regular intervals.If it is increasing & after reboot it is coming down, it has memory leak problem, you should be able to find bug releated to this .

If it is memory leak problem, you need to upgrade it to stable IOS.

The memory utilization is normal. My NMS report showing no abnormality in CPU/memory usage.

Router reload two weeks ago and then last night it reload.

I have configured the router as blocking device in cisco IPS and i think after configuring this i m started facing this problem.
