urgent problem [7:14942]
i have router 3640 with 12m processorr memory and 4M I/o memory running ospf process suddenly i can not telnet soemtimes it works sometimes not and when i log to console i find that there is a problem in its memory allocation here are some show comands it might help please advice as soon as possible i want to know is it bug in IOS or memory leakage or harware failure %SYS-2-MALLOCFAIL:memory allocation of 128975 bytes failed from 0x601451F8, pool processor alignment 0 %Low-on-Memory R002#sh ver Cisco Internetwork Operating System Software IOS (tm) 3600 Software (C3640-I-M), Version 11.2(7a)P, SHARED PLATFORM, RELEASE SOFTWARE (fc1) Copyright (c) 1986-1997 by cisco Systems, Inc.

Re: urgent problem [7:14942]
Yeah - I've had a similar problem with a 3640 running 11.x code. Up it to 12.0.18 if you can and it should go away. Mine has been rock solid ever since. Other things I noticed, besides the intermitant connectivity, would be that the whole box would hang while you were on it for periods of time. Then it come back like nothing ever happened. All related to memory allocation.

Re: urgent problem [7:14942]
Generaly, memory leaks are not hardware related. They're code related. Either way, the only real way of isolating them is process of elimination. Which means, turn down extra services, update OS, etc. Since I doubt you can turn down any extra services without impacting your users, upgrading to see if it goes away is the next simplest without impacting everyone (other than for the reload of course). You could also just search CCO or call TAC and see if there is a known issue with that revision of code as well.

Re: urgent problem [7:14942]
It appears that 16MB of RAM just isn't enough for your interface requirements. During you sh mem it states that 97K is free, the MALLOC is for 128K. This 128K of memory must be in a single contiguous chunk. The largest chunk of memory is 33K. The number of interfaces on the router is rather high, for the amount of memory installed. You need to take a look at the 2600/3600 Memory Calculator: http://www.cisco.com/cgi-bin/Support/MemCalc/mem-calc.pl I took a look and attempted to configure a 3640 with the Interfaces describe in the sh ver and got 24MB of DRAM required.
