ISM-VPN background in ISR 3925

Hi,

I have a 3925 router running  with an "ISM-VPN background process" which is running high and causing the CPU to spike up to 80%.  There is a ISM-VPN card on the router as well.

IOS version on router "c3900-universalk9-mz.SPA.153-1.T.bin"

Seems like this might be an undocumented bug but I'm curious if anyone else has seen this issue before.

Appreciate any insights that can be provided.  Thanks!

Hi,

I had this issue, it was due to the crypto engine failing, below command will show if it has an issue,

sh crypto engine configuration

If there is and issue it will show as HW State : DEAD, the only way I found to re-enable it was to reload the device.
