public final Acceptor.AcceptorState getState()

run

public void run()

Specified by:

run in interface Runnable

stop

@Deprecated
public void stop(int waitSeconds)

Deprecated.

Unused. Will be remove in Tomcat 11 onwards.

Signals the Acceptor to stop, optionally waiting for that stop process to complete before returning. If a wait is requested and the stop does not complete in that time a warning will be logged.

Parameters:

waitSeconds - The time to wait in seconds. Use a value less than zero for no wait.

stopMillis

public void stopMillis(int waitMilliseconds)

handleExceptionWithDelay

protected int handleExceptionWithDelay(int currentErrorDelay)

Handles exceptions where a delay is required to prevent a Thread from entering a tight loop which will consume CPU and may also trigger large amounts of logging. For example, this can happen if the ulimit for open files is reached.

Parameters:

currentErrorDelay - The current delay being applied on failure

Returns:

The delay to apply on the next failure
