Hi
I have 3845 router where 200 branches are connect. Ho have database server where branch are synch interval period.
some of days observation cpu load average 70 % and sometimes it reaches 100 %.
yesterday when I give command clear arp then instant cpu load reduce and 20 %
yesterday cpu load 12-20 %. Today morning when I give command Cpu proc history
then I found cpu load 60 % and at night it was 3 times reaches 100 %.
so my question is after clear arp command at least 10 hours cpu utilization 20 % but after that it increase.
so for any LAN broadcast it happend ? how i understand cpu high for Broadcasting or anything else.
have any solution.
Regards

Hi,
If you don't have information about the way applications used on branches work, you need to a packet analyzer utility. This would definitely help you out to determine the cause of this problem.
