B-E Package 4.5 loses subscriptions

The following has been experienced at two different companies.

The B-E Package loses subscriptions to the events it is supposed to process. Various techniques can be used to re-establish proper operation (restart the adapter, touch one of the integrations) but these are stop-gap measures. We’ve been unable to identify the root cause nor a permanent solution. One theory is that changes to event types can cause this symptom but this doesn’t seem to be consistent.

This is with 4.1 and the 4.5 B-E Package.

Anyone else experienced this and found a permanent solution?
