Memory problems on my Cisco 1720

Hello I attempted to make some adjustments,which did not take, to my VPN. Subsequent to those attempts, my router periodically stops functioning and needs to be reloaded. At my first attempt to console after one of these episodes I get the message "low memory - try again later".

When the router comes up it complains in the following manner:

cisco 1720 (MPC860T) processor (revision 0x601) with 27853K/4915K bytes of memory.

Processor board ID JAD061301QE (2828269743), with hardware revision 0000

MPC860T processor: part number 0, mask 32

Bridging software.

X.25 software, Version 3.0.0.

1 Ethernet/IEEE 802.3 interface(s)

1 FastEthernet/IEEE 802.3 interface(s)

1 Virtual Private Network (VPN) Module(s)

32K bytes of non-volatile configuration memory.

8192K bytes of processor board System flash (Read/Write)

Memory configuration adjustment:

Image size=21863296, PMem req=27329120, I/O mem=6710272, PMem avail=26844160

Warning: Attempting a memory percentage that does not provide enough Processor memory for the currently running image. If you save your running-config now,

this version of software may not be able to run.

% VPDN is not enabled

------------------------------------------------------------------------------------------------------

Pmem req is larger than Pmem avail??

It reloads twice and is operable on the second reload.

Has anyone seen this before?

Thanks in advance.

Has the router been upgraded? Seems like a good idea to check memory-requirements for your current release, which you did not include in the posting.

Re: Memory problems on my Cisco 1720

I am told that the router was upgraded 6 months ago. In any case I have included the results of "sh flash".

Cisco1720#sh flash

System flash directory:

File Length Name/status

1 7289632 c1700-k9o3sy7-mz.122-8.T1.bin

2 814 running-config

3 4342 good-config

4 4320 startup-config

5 4337 ciscp-171002

[7303772 bytes used, 1084836 available, 8388608 total]

8192K bytes of processor board System flash

-----------------------------------------------------------------------------------------------------

What else could I post to fix this.

Re: Memory problems on my Cisco 1720

Your router doesn't have enough memory to run the current software image.

You need at least 48 MB Dram Memory to run this image properly

This is the info i got from the cisco site :

Image Name (Dram/Flash) : c1700-k9o3sy7-mz.12.2-8.T1 (48/8)

What you need is an memory upgrade.
