Media for Picking an IOS for a 2500

Picking an IOS for a 2500

I have a 2514 being used for my ADSL connection with a few servers behind it and running: IOS (tm) 2500 Software (C2500-IS-L), Version 12.3(15a), RELEASE SOFTWARE (fc2)

The pppoe connection works perfectly from the first go at it, however, there is a slow but noticable memory leak. After reloading, I have a little over 7 megs or RAM. After 12 to 24 hours, I'm already down to: Nimiety>sh mem Head Total(b) Used(b) Free(b) Lowest(b) Largest(b) Processor 1BD228 12852696 9674688 3178008 3178008 3178008 I/O E00000 2097152 392580 1704572 1704572 1704212

As a result, I have to keep an eye on things and reload the router at a quiet point traffic-wise every two days or so. I've been trying to find an IOS that will support the protocol pppoe under the VPDN command set, but although several of the versions that I've tried say they do, I get unrecognized commands after upgrading and reloading under the new version. I end up having to back out and stay with the original IOS above. I've tried c2500-is-l.122-31.bin and a few others but all to no avail.

So my options are to either somehow fix the leak (which may be caused by some odd command, but I'm doing little of exitement other than NAT), or to find an IOS which supports the protocol pppoe command and hope that it works and doesn't leak.

Any advice or suggestions? Thank you in advance! James..
