heartbeat log: Cannot create ID for application, because appId range is exhausted. Application will be ignored.

Question

is that something to worry about in the heartbeatd.log? This is logged quite frequently on our SFOS 19.0.1 box [2023-03-16 14:18:04.039Z] INFO EndpointStorage.cpp[32722]:110 endpoint_connectivity_cb - Connectivity changed for : <3> -> <4> [2023-03-16 14:18:05.597Z] ERROR SacProcessor.cpp[32722]:100 handleApp - Cannot create ID for application, because appId range is exhausted.

Just wantred to know if we need to get something fixed on heartbeat before.

There is a switch to cleanup old / unused apps: Do you have this enabled?

Cleanup is will not restart the heartbeat. 
 Yes, data sync expected to happen on Auxiliary node.

Hi LHerzog , 
 We have planned to solve the appid exhaustion issue in our upcoming v20 release. The solution will start reusing the deleted appids once the max appid is already used. This solution will also include actual deletion of the appids. 
 Currently as a part of auto-clean, we are deleting all application related data to free up storage but not deleting the appids. This was done to ensure we reuse the same appid for the same application that gets detected in future. This delays the appid ranges to get exhausted. However once the appid range is exhausted, we have a problem that is getting solved in v20 release.
