Hi guys,

I have a 831 router with this little problem: It crashes.

I did some analyzing and I realized that memory is running out (actually draining). This is the info:

Cisco IOS Software, C831 Software (C831-K9O3SY6-M), Version 12.3(2)XE, EARLY DEPLOYMENT RELEASE SOFTWARE (fc1)

NLUSHQROUTER02 uptime is 1 day, 6 hours, 28 minutes
System returned to ROM by power-on
System image file is "flash:c831-k9o3sy6-mz.123-2.XE.bin"

Cisco C831 (MPC857DSL) processor (revision 0x400) with 44237K/4915K bytes of memory.
Processor board ID AMB08210D7P (3292041264), with hardware revision 0000

128K bytes of NVRAM.
12288K bytes of processor board System flash (Read/Write)

Configuration register is 0x2102

If you see the uptime... you'll realize this happening quite often.

some mem stats:

some proc memoray usage... that cought my attention:

What is the chunk manger? I was thinking of an IOS upgrade to see if this fixes the memory drain. Anyone agrees?
