All Implemented Interfaces:

Serializable, CommandKnowledge

public class CompletionTimeOut
extends TimeOutError

An error event signaling a command that was not completed in time. This indicates that either the network went down, the command server has blocked, or the command took longer to be completed than expected. The latter case is the most easiest one to handle, simply increase the completion time transfered with the previous acknowledge.

In the current implementation this error is considered rather severe (level 6) and the recovery strategy initiates a shut-down sequence.
