Description (partial) 

Symptom:
During an unplanned MIO switchover, it is possible for the CSPCtrl task to take extended times to recover which can impact interface recovery thus potentially causing an ICSR switchover.

Conditions:
When demux-on-mio functionality is enabled, the cspctrl task can take longer to recover. If this recovery takes longer thatteh srp dead interval, this will cuase an ICSR switch over to occur.
