Yeah, I got some 12.4 code for it, but it doesn't currently have enough
flash ram to hold that. I upgraded it for 12.3(6) to 12.3(23), we'll see if
that helps.

I think you can actually get recent 12.4 code for it. Not the latest, but
close. Could be a memory issue with it, a DOS against it, etc. Reseating
the modules and memory and trying a more recent IOS might all help.

We have a cisco 3600 that has rebooted twice in the last two hours,

I checked "show mem" and nothing is listed as operating that address,
at least not right now. This router has been in operation a long time
and has not had these problems previously. Nothing has changed in the
config on the router in the last several months, at least.
Another possibility is that the version of code you're running is vulnerable
to one (or more) of the many bugs that can cause a Cisco router to reload,
leak memory, etc. 12.3(6) is pretty ancient code, and the
3640 has been end-of-life since 2007, and no new code has been released for
it since probably late 2005.
I don't know what function this router serves in your network, but replacing
it with something newer that can run newer code is worth considering,
epecially if it's something that can be reached from untrusted networks.
