Like Richard mentioned, it may be interfaces, either physical or
logical. Depending on where it's crashing, it may be the config. Did
you recently add any functions like NBAR, or maybe they're taking in
more routes via a protocol than they were before. Assuming you don't
have a 'memory-size iomem xx' command in the config, you're probably
running out of processor memory, as smart-init is deciding how much
memory to dedicate to the interfaces. Boot one up without a config, and
do a 'sh ver'. Note the memory line, where the two numbers should add
up to 48 megs. The smaller number on the right is what's being given to
the interfaces. Calculate the percentage. It may be 25, or it may be
less. Now add the line 'memory-size iomem x' where x is the multiple of
5 one less than what you computed. So if the calculated percentage is
20, set it to 15. Then reboot it. Now paste in the original config and
see if it works. Once it's working right, do a 'sh mem'. You can keep
reducing the memory percentage by multiples of 5 until you're down to
about 1 mbyte of memory free for IO. HTH.

Subject: OT: 48MB 2600s no longer booting 12.2(19a)
Hi,
About six months ago I upgraded some non-XM 2600s using the
c2600-jk9o3s-mz.122-19a.bin image. Although 64MB RAM is recommended,
48MB seemed to work OK with this image. Now, six months later some of
these routers no longer want to boot this image and are complaining
about not enough memory. What could be causing this "delayed reaction"?
I'm at a loss to explain why the IOS could boot one day but not the next
when the hardware has not changed. Cosmic rays? :-)
Thanks
