I have a problem with a Cisco IOS IPS
to turn on the interface approximately after 12 hours the device is locked and you need to physically reboot.
and restarts when the interface is disabled equipment is operating properly, the category that is enabled is the basic.
The router is a cisco 2901
IOS: c2900-universalk9-mz.SPA.150-1.M6.bin
