I think you may consider to upgrade the memory. If you use some feature set such as rpf-check, it will build another set of table to consume the memory. So if you use rpf-check, you can disable it to decrease heap memory utilization problem. But eventually if you want to hold full routing table, you may have to upgrade the memory to 128M. I think M10 FEB can be upgrade up to 128M.

The FEB shows: FEB status: Temperature 27 degrees C / 80 degrees F CPU utilization 11 percent Interrupt utilization 19 percent Heap utilization 96 percent Buffer utilization 61 percent Total CPU DRAM 64 MB Internet Processor II Version 1, Foundry IBM, Part number 9 and even the arp count is similar: > [EMAIL PROTECTED]> show arp no-resolve |count > Count: 411 lines > > > show arp no-resolve | count Count: 461 lines It seems there is not problem related to prefix count: sh jtree 0 onchip summary Protocol Routes Bytes Used ------------- ---------- ---------- IPv4 248927 3599360 IPv6 1177 20896 MPLS 1 16 Multi-service 1 16 If this problem can be related to software version or features enabled on the router - is there any way to decrease Heap utilization by disabling some unnecessary functions? Can this lead to the packet drops?
