High speed logging (HSL): asymmetric bandwidth loss might result in no bandwidth tracking.
For a period of time after the logging node comes back up, HSL::send events will not be sent to the log server. Sometimes it never recovers and tmm needs to be restarted.
This will occur if the log server pool only has a single member in it, and that member goes down and up while HSL::send is occurring during traffic processing.
If possible, configure log server pools with multiple members to avoid this condition.
