2811 High Memory Usage

Hello,

   We just connected a new 2811 at one of our remote sites.  All L2 traffic is tunneled back to campus via an IPSEC tunnel.  In the last few days I have notice that the 2811 is experiencing very high memory usage (89%).  Currently there are only 6 computers connected to the switch module on the router and bandwidth usage is very low.  How would I determine what is causing the high memory usage?

Thanks

Mike

Looks like CSCta09049 to me. The fix should be in 12.4(22)T5 or 12.4(24)T3.

HTH,

Those commands will help me to find out the problems.

Can I see the show version to see what IOS you are running?
