Symptoms

While connected to a node Ethernet service port via Serial Over LAN (SOL) using IPMItool the connection may become unresponsive. This may be observed during a node reboot.  After a period of time you receive an error: 
ipmitool -I lanplus - C 3 -H 128.221.1.252 -U console -P <service_tag> sol activate
Error activating SOL payload: Unspecified error
 

Cause

This happens when the connection drops but remains active. For IPMI/SOL, only one single connection to the same device is possible.

Resolution

You must manually end the SOL session (deactivate) and activate it once more: 
ipmitool -I lanplus - C 3 -H 128.221.1.252 -U console -P <service_tag> sol deactivate
  
Activate the SOL session again with:  
ipmitool -I lanplus - C 3 -H 128.221.1.252 -U console -P <service_tag> sol activate
[SOL Session operational.  Use ~? for help]
