Description (partial)

Symptom: 2125 auto reboots during software image download 
Conditions:In the event that multiple management sessions (ssh, telnet, webUI) are concurrently opened against a 21xx controller,
the system can reserve up to 2 MB of memory per session. Depending on the number of concurrent sessions, it can result in reservation of significant amount of memory, which is then no longer available during image downloads. 

As a result, it is advised that free system memory of at least 90MB be ensured (show memory statistics prints this information on the CLI) before doing image downloads on 21xx platforms.
If the memory is depleted below 90M due to above reason, the system will need to be re-booted
before doing an image download.
