The following events may be emitted within this span:
[:thousand_island, :acceptor, :spawn_error]
Thousand Island was unable to spawn a process to handle a connection. This occurs when too many connections are in progress; you may want to look at increasing the
num_connections
configuration parameterThis event contains the following measurements:
monotonic_time
: The time of this event, in:native
units
This event contains the following metadata:
telemetry_span_context
: A unique identifier for this span
[:thousand_island, :acceptor, :econnaborted]
Thousand Island was unable to spawn a process to handle a connection since the remote end closed before we could accept it. This usually occurs when it takes too long for your server to start processing a connection; you may want to look at tuning OS-level TCP parameters or adding more server capacity.
