I have router running 12.4(24)T2, RELEASE SOFTWARE (fc2) and I have had devastating results issuing a 'clear counters s0/0/0' command.
This knocked out my MPLS connection! What am I doing wrong? It has happened to me twice now at 2 different remote locations. Not good for the career. Anybody have the same issue ever? Thanks[

do you have any logs on the router we can look at before and after you did a clear counter?

Hi,
Please use "clear counters" in privilige mode only. This will clear counters on all interfaces.
I used to do this many times without any disconnects.

Hi,
Please use "clear counters" in global config mode. This will clear counters on all interfaces.
I used to do this many times without any disconnects and this is recommended as per best practice.

The issue may lie in the configuration of the serial interface:
interface Serial0/0/0
description TO AT&T MPLS ID:
ip address 172.16.2.25 255.255.255.252
ip flow egress
encapsulation ppp
service-module t1 clock source internal
service-module t1 timeslots 1-24
service-policy output VOIP
Someone was saying that the clock should be line on a serial interface.
I am going to the site this weekend so will issue command from console and check results.
also plan on opening a tac case for this.
version is 12.4(24)T2, RELEASE SOFTWARE (fc2)

Just about any time you get serial carrier services, you should take clock source from the line - not internal.
watch some of your low level counters (frame crc0 disappear after you change
