[c-nsp] memory issue asr1002-x

Wed Nov 22 06:09:13 EST 2017

 Ya, but i think the critical is the IOSd memory. Wondering the IOSd has the features of using based linux swap memory?

does not look like it on this box:

Router#show version | i mem
cisco ASR1001 (1RU) processor with 6848986K/6147K bytes of memory.
32768K bytes of non-volatile configuration memory.
16777216K bytes of physical memory.

Looks like you are right.

I OP has an ASR1002-X, check one here:

#show ver | inc mem
cisco ASR1002-X (2RU-X) processor (revision 2KP) with 3729028K/6147K
bytes of memory.
...
8388608K bytes of physical memory.

^ This only has 8GB of RAM and it is using roughly half as expected.

Although not using half isn't exactly a bad sign in its self, the
Linux virtual memory manager allows for memory overcommit:

#show platform software status control-processor
Memory (kb): healthy
  Total: 8091848
  Used: 3885636 (48%)
  Free: 4206212 (52%)
  Committed: 5328504 (66%), status: healthy, under 95%

So it maybe that IOSd on OP's system would simply grow more when needed?

Cheers,
James.

  Hi Guys,
Thanks for replying. The iosd i checked is a 64bits IOSd. 
i suspect is my license issue. possible?

cisco ASR1002-X (2RU-X) processor (revision 2KP) with 3553107K/6147K bytes of memory.

32768K bytes of non-volatile configuration memory.

16777216K bytes of physical memory.

 Hi David,
Thank you for replying.Ya the memory allocated 3.5gb to IOSD from the platform is unusually strange. It should be 6.5gb based on 16gb memory router.
Just asking the community if anyone has solve/encounter the same problem.Unfortunately, this router i took over from someone and there is no smartnet available.

Hi Caroyy,

I believe that the IOSd process is a 32-bit process so it can't use
more than 4GBs of RAM.

does not look like it on this box:

Router#show version | i mem
cisco ASR1001 (1RU) processor with 6848986K/6147K bytes of memory.
32768K bytes of non-volatile configuration memory.
16777216K bytes of physical memory.
Router#

Try looking at the output of "show redundancy".  The ASR1000 had some kind of IOS redundancy feature to run two IOS processes on a box splitting up memory between them.

Greetings
Christian

 This is how much memory has been assigned to iosd. Show version will display memory allocated to iosd and the total memory installed.
