Description (partial)

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.

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.
