remote_slifrecv: Limited expansion room - packet lost and crashed PM

Hrrrm... we happened to have someone here camping on a PM2ER30 when it rebooted
itself. This is with ComOS 3.5.

It looks like something is seriously confused, perhaps a buffer overflow in the
code somewhere?

Could it be related to this one line, received about 3 minutes before it
rebooted: remote_slifrecv: Limited expansion room - packet lost

Show memory right now shows:
System memory 1048576 bytes - 1000416 used, 48160 available
2048:3 1152:2 640:2 144:3 80:2 4240:3 48:3 16:35 128:3 160:3 32:1
System nbufs 1400 - 308 used, 1092 available

The number of free nbufs seems fine and dandy: the 48k left doesn't, but it
seems constant and is only a few K less than another 2ER30 I just looked at.

[Tail of the window that was open .. and use we use the LCP_ECHO's... it works
wonders to take down a T1 fast when it loops... Silly Cisco by default thinks a
looped PPP is okay and not a problem.]
