Re: Router 7613 Hang

Hello Jayesh,

>> %SYS-3-CPUHOG: Task is running for (3244)msecs, more than (2000)msecs (79/5),process = PPP manager.

this means a process, PPP manager, has used main cpu for 3244 msecs more then the maximum allowed 2000 msecs.

there is a feature called whatchdog that is authorized to reboot the device when the cpu time is much more then the stated threshold.

in your case this has not happened.

Check your device configuration and see what it is doing with PPP for example if it is terminating users this can happen if you have just serial or POS links with PPP encapsulation this shouldn't happen.

Hope to help
