100% CPU Utilization may indicate encryption key generation is in-progress

There may be instances when a “display device” command returns a CPU

utilization of 100%. A CPU usage this high may indicate that encryption key

generation is in-progress. On initial boot, the Digi device generates some

encryption key material: an RSA key for SSL/TLS operations, and a DSA

key for SSH operations. This key-generation process can take as long as

40 minutes to complete. Until the corresponding key is generated, the Digi

device will be unable to initiate or accept that type of encrypted connection.

It will also report itself as 100% busy but, since key generation takes place

at a low priority, the device will still function normally. On subsequent

reboots, the Digi device will use its existing keys and will not need to

generate another unless a reset to factory defaults is done, which will

cause a new key to be generated on the next reboot.

Required
