Please log in for more thread options 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.. | |||||||||||||||||||||||||

I would have thought so, but no - late collision messages (I'm using the aui ports, so their 10/half, perfectly normal) and rarely (once a week) an AAA error about memory allocating, but I recall it seemed reevant for accounting logs and not packet processing, et al. If I see another one, I'll post it in, but I'm seeing fairly heavy traffic continuously, and I would have thought memory problems would hit the logs as frequently as the memory dropped, which is continuously. 5 minute input rate 26000 bits/sec, 4 packets/sec 5 minute output rate 20000 bits/sec, 4 packets/sec Nimiety>sh mem

That looks helpful - I will certainly review it closely. I've also just enabled CEF to see if that helps slow the leak down. I have a tiny routing table (nothing dynamic, only a few statics), and the router itself has 16M/16M, which is the max for the 2500 chassis, if I'm not mistaken. I find it interesting that there's no fragmentation ever to the memory (free, lowest and largest are always equal). There does seem to be a fair amount of dead memory: Nimiety#sh proc mem Total: 14949848, Used: 11611408, Free: 3338440 PID TTY Allocated Freed Holding Getbufs Retbufs Process 0 0 106608 0 3497036 0 0 *Init* 0 0 272 0 272 0 0 *Sched* 0 0 5308612 0 5548 378300 0 *Dead* but those figures don't increment the way show mem (or show mem sum) decrease. Regardless, any additional info on suggested IOSs, or an explanation why a command which should work and doesn't in practice, would be very appreciated! James... | |||||||||||||||||||||||||
