The root cause is frequently a […]

Resolving Ruby EventMachine reactor block due to synchronous I/O operations Under Peak Event Traffic on DigitalOcean

Diagnosing EventMachine Reactor Blockage Under Load When an EventMachine-based Ruby application experiences intermittent unresponsiveness, particularly under peak traffic on platforms like DigitalOcean, the primary suspect is a blocked EventLoop reactor. This blockage typically stems from synchronous I/O operations or long-running CPU-bound tasks that prevent the reactor from processing subsequent events in a timely manner. Identifying […]
