Description (partial)

The stp_io process abnormally restarts during a config rollback operation, or after router communications outage.

Repeated configuring and unconfiguring of MSTP instances on different bundle interfaces results in stale database entries being created on the standby RP. If, after a switchover, a resync of the stp-io database is triggered, stp-io may crash as a result of these stale entries.

This is only seen with x86-based RSPs when MSTP is used over bundle interfaces.
