Silo diagnostic events
The generated ErrorCode API reference tracks the runtime’s current silo event definitions. The error-code source on the main branch shows definitions under active development.
Search for the structured event ID in ErrorCode, then use its log category, exception, and surrounding metrics to select a remedy:
| Diagnostic area | Remedy |
|---|---|
| Membership, missed pings, silo status, or grain directory | Membership and directory churn |
| Message rejection, unavailable silo, connection, or gateway | Silo unavailable or message rejected |
| Scheduler or long-running activation turn | Long-running or deadlocked grain turns |
| Storage provider, state version, or throttling | Storage consistency failures and Storage throttling |
| Serialization or codec | Serialization failures after a version change |
| Reminder or timer | Reminder and timer timing |
| Overload, rejection, memory, or shutdown | Orleans symptom and signal catalog |
