MongoDB Error 253: Monitoring HTTP Request Limit
Description
Error 253, 'Free Mon Http In Flight', indicates that MongoDB's internal mechanism for sending monitoring data has reached its limit for concurrent HTTP requests. This typically occurs when the system attempts to initiate more monitoring data transmissions than allowed, causing new requests to be blocked.
Error Message
Free Mon Http In Flight
Known Causes
3 known causesExcessive Monitoring Activity
The MongoDB instance is configured to send monitoring data too frequently or is generating an unusually high volume of monitoring events, exceeding the allowed concurrent HTTP requests.
Monitoring Connection Pool Exhaustion
The internal HTTP client's connection pool, used for transmitting monitoring information, has become saturated with pending requests, preventing new 'in-flight' operations.
Network Bottlenecks or Latency
Slow or unstable network conditions can cause monitoring HTTP requests to remain 'in-flight' for extended periods, consuming all available concurrency slots and preventing new requests.
