ASR1001 High Memory Utilization


I have an ASR1001 showing very high memery utilization in the last 8 months. SolarWinds shows 94% all the time.

The top 3 processes using the memory are: linux_iosd-imag (25.9%), fman_rp (21.4%) and fman_fp_image (17.4). The first is for the IOS image. What are the other 2? Does this show a potential problem?

Hi Larry, Since last 8 months

Hi Larry,


Since last 8 months memory utilization is high only, i dont think there is any memory leak. It could be genuine memory utilization as well and we need to do memory upgrade. Do you have any similar box with similar configuration and less memory utilization? Please provide below output


- show version

- show processes memory sorted

- show platform software status control-processor brief

- show platform software process list rp active sort memory 

- show platform software process list fp active sort memory
