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

Definitely should be running something newer, given the number of
vulnerabilities that old IOS has in it.  We've had good luck with 15.0(2)SG
on these platforms.   SG10 looks to be the latest available.  That does have
an NTP vulnerability in it from earlier this year, but I'm told SG11 will
fix that, and be available sometime in July.  SG10 would be a good choice.
Google 'IOS memory usage' and you should find a bunch of articles to
troubleshoot.  But upgrading is probably the smartest thing to try.

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.
