[c-nsp] ASR9000 and ssh and "Crypto enginer decrypt failed"

[hank at interall.co.il]

On Sunday May 31 at around 7:34-7:36 (GMT+3) both of our routers  
started showing the following error msg:

RP/0/RSP0/CPU0:May 31 07:36:56 : syslog_dev[94]: locald_DSC[328]  
PID-217213: ce_pubkey_authenticate: Crypto enginer decrypt failed: No  
child processesce_pubkey_authenticate: Crypto enginer decrypt failed:

decrypt failed: No child processesce_pubkey_authenticate: Crypto  
enginer decrypt failed: No child processesce_pubkey_authenticate:  
Crypto enginer decrypt failed: No child proces
sesce_pubkey_authenticate: Cryp


At the same time ssh to and from these routers started to become wonky.

I am unable to find this error in Cisco IOS-XR documentation and the  
fact that it appeared at the same time in both routers leads me to  
suspect that perhaps they were probed by some crafted packet that  
caused it so  I am wondering whether other IOS-XRs have seen a similar  
error message.

Thanks,
Hank
