TMM panics with the assertion 'nexthop ref valid' failed. This occurs after a large number of remote picks cause the nexthop reference count to overflow.
TMM restarts. Traffic is interrupted.
An LSN Pool and remote picks. Remote picks occur when the local TMM does not have any addresses or port blocks available. Remote picks are more likely when inbound and hairpin connections are enabled.
There is no workaround.
TMM no longer panics regardless of the number of remote picks.
