OSPF Process Excessive memory use

mcopelin

We have two Cat6509 switches in a fairly simple HSRP arrangement. They have identical configuarations. This worked well until about a week ago when I

started to get memory allocation errors for OSPF and virtual exec processes

on one of the MSFC's. We upgraded the DRAM to 128MB and MSFC is running ok EXCEPT the OSPF process is holding roughly 20MB memory. Every other 6500 on our network, (including its HSRP partner), in the same OSPF area are holding bewteen 2-4 MB for the OSPF process. Has anyone seen this type of behaviour before?

There might be a possibilty that when you checked the memory consumed the OSPF calculations might have been taking place and hence the memory utilization could have gone high. Is this consistent? However, Version 12.1(2) E has a bug with OSPF memory fragmentation.CSCdr70471. Check the Bug Toolkit for details. Not sure if this could be the reason for memory consumption. Try upgrading your IOS. Might resolve the issue. Let me know if this works!
