Ik krijg bij het opstarten van mijn Cisco 1605-R Router een SYS-3-CPUHOG waarschuwing. Hieronder heb ik de hele waarschuwing gepaste:
Op de officiele cisco site vond ik deze info:

Wat betekend dit en wat kan ik hier eventueel aan doen?00:00:48: %SYS-3-CPUHOG: Task ran for 2076 msec (0/0), process = IPSEC key engine, PC = 20C0A2A.

Op de officiele cisco site vond ik deze info:
Bij mij vind de CPU-Hog niet plaats op de "boot load" maar op de Ipsec. Ik kan hier echter niets over vinden.To reduce the impact of runaway processes, Cisco IOS® software uses a process watchdog timer to allow the scheduler to periodically poll the current running process. This feature is not the same as preemption, but is instead a fail-safe mechanism to prevent the system from becoming unresponsive or completely locking up due to a process consuming all of the CPU.
If a process appears to hang (for example, if it's been running for a long time), the scheduler can force the process to terminate.
Each time the scheduler allows a process to run on the CPU, it starts a watchdog timer for that process. After a preset period, if the process is still running, the watchdog process generates an interrupt and causes a router restart by a "software forced crash" (the stack trace shows a watchdog process as the trigger of the crash).
The first time the watchdog expires, the scheduler prints a warning message similar to the following:
%SYS-3-CPUHOG: Task ran for 2148 msec (20/13), Process = IP Input, PC = 3199482
-Traceback= 314B5E6 319948A
This message indicates the process that is holding up the CPU. Here, it is the "IP Input" process. This message usually appears during transient circumstances, such as an Online Insertion and Removal (OIR) during the bootup process of the router or under heavy traffic conditions. These messages should not appear during normal operation of the router.
The accounting of the time a process ran may not be accurate if the router is busy at interrupt level after a process was scheduled to run because the CPUHOG only tracks process level tasks, not interrupt level tasks which are permitted to interrupt and gain control of the CPU. The typical process to run at interrupt level is packet switching.
CPUHOG during the Bootup Process
CPUHOG messages during the boot sequence are fairly common. The error message itself means that the boot process has held the CPU just a little longer than the system wanted it to, and then has sent a message to the console output to let you know. The process in this case is "Boot Load," which indicates where the CPUHOG occurred.
