parts of config missing, then back

I've noticed an occasional bug, where for some reason rancid will lose
large parts of a config (seems to only happen on Cisco AS5200's so far).
Eventually, the missing config (or parts of it) comes back. i.e.

In the past couple of runs for one particular 5248, first 70 lines of
config vanish (everything in interface Ethernet0 other than the interface
name, most of interface Virtual-Template1, and the entire sections for
interfaces serial0, serial1, serial0:23, and serial1:23). Some number of
runs later, the serial interfaces return, but the missing config data from
Ethernet0 and Virtual-Template1 are still gone. I'm running do-diffs
hourly, so somehow the same incomplete config is downloaded multiple times
before returning to normal.

Anyone seen this before?

i've seen boxes that ommit their configs at random. usually related
to memory shortage.

if you cant get it to do it manually, i'd suggest setting NOPIPE=YES
in bin/env and add a cronjob that copies the 5200_hostname.raw file
to a separate_dir/5200_hostname.raw.time. so you can verify that its
not (or is) rancid or the box. and you can prove it to cisco :)

That would be it. Good old MS IOS leaking memory.
