Hello Joshi,

>> Jul  9 23:57:17: %SCHED-3-STUCKMTMR: Sleep with expired managed timer 62F982C0, time 0x9200D1E54 (00:00:00 ago).

-Process= "URL filter proc", ipl= 4, pid= 76

-Traceback= 607BE084 607BE4DC 608E59E8 608E5C9C 608E93F8 6098D808 609932AC 61068A18 6106953C 610680E4 61068470

the process URL filter uses too much cpu time. There is a protection mechanism called watchdog that actively monitors cpu usage by other processes.

When a process stucks the cpu the watchdog may even trigger a reload in an attempt to free the main cpu resources.

you have a quite old NPE on it if it has only 128 MB  of RAM I'm afraid you cannot use this feature on this box, not without some tuning at least.

the feature may not be supported on your IOS image and hardware.

for going you should provide additional information

show ver

+

configuration of URL filtering and for what you use it

do not post usernames/passwords and change public ip addresses in private ip addresses for your safety.

Hope to help

Hi,

URLF-3-SERVER_DOWN:Connection to the URL filter server  10.40.2.26 is down

In this message, the router has lost contact with the  content-filtering server (10.40.2.26). If you have configured a secondary  server, the router establishes contact with it.

%URLF-3-ALLOW_MODE:Connection to all URL filter servers are down and ALLOW MODE is OFF

If the primary (or secondary) servers fails and no other  content-filtering server is available, you will see this message. The  router goes into an allow mode, in which all HTTP connections either are  allowed or are denied.

%URLF-5-SERVER_UP:Connection to an URL filter server  is made, the system is returning  from ALLOW MODE

If CBAC inspection for HTTP has entered the allow mode and then  successfully restores connectivity to a content-filtering server, you  will see this message.
