Exception	Reason	Fix
`EventHubsException` (ServiceTimeout)	Service didn’t respond in time	Transient — retried automatically. Verify state if persists
`EventHubsException` (QuotaExceeded)	Too many active readers per consumer group	Reduce concurrent receivers or upgrade tier
`EventHubsException` (ConsumerDisconnected)	Higher priority consumer took ownership	Expected during load balancing; check if scaling
`EventHubsException` (MessageSizeExceeded)	Event too large	Reduce event payload; unlikely in practice since the client caps at the service link limit
`UnauthorizedAccessException`	Bad credentials	Verify connection string, SAS token, or RBAC roles
