[c-nsp] WS-C4948-10GE Memory leak

[Jason Berenson]

Greetings,

I have a pair of WS-C4948-10GE both running 
cat4500-entservicesk9-mz.122-52.SG.bin.  One has been up for almost 7 
years with no issues.  The other has to be rebooted every few months 
because of a memory leak.

Both are customer facing routers running some basic BGP/OSPF and IPv6.

Is there a newer IOS I should be running?  Any commands that might shed 
some more light on this?

Thanks in advance.

Jason.
