An AbEnd (also abnormal end or abend) is an abnormal termination of software, or a program crash. This usage derives from an error message from the IBM OS/360, IBM zOS operating systems. Usually capitalized, but may appear as "abend". The most common were ABEND 0C7 (Data exception) and ABEND 0CB (Division by zero). Abends could be "soft" (allowing automatic recovery) or "hard" (terminating the activity).
Adding scalability and fault tolerance to generic finite state machine frameworks for use in automated incident management of cloud computing infrastructures
InactiveUS20120151272A1Program controlRedundant operation error correctionFault toleranceExtensibility
A scalable and fault tolerant finite state machine engine, for example, for use in an automated incident management system, logs or records data in persistent storage at different points or levels during various internal processing of an event associated with an information technology element, and action taken associated with the event, by executing a finite state machine instance that encodes policies for handling incidents on such types of information technology elements. In the event that the finite state machine engine is shutdown during processing, the finite state machine engine is able to pick up from where it left off when it was shutdown, for each abnormally terminated finite state machine instance, by using the data logged in the persistent storage and determining a point of processing from where it should continue its execution.

Method and system for intelligent and adaptive exception handling
A method and system for handling errors and exceptions in an ERP environment are disclosed. According to one aspect of the present invention, a condition or event causes a script-engine associated with a particular ERP server to generate an error message. The error message is communicated to a centralized controller-node. The centralized controller-node analyzes the message and determines the best course of action for handling an error or exception related to the error message. Based on the controller node's analysis, the controller node communicates a response message, thereby enabling the process that caused the error to continue without terminating abnormally.

Method and system for transmitting data for data synchronization between server and client when data synchronization session was abnormally terminated
InactiveUS20050235019A1Lighting elementsData switching by path configurationData synchronizationClient-side
Disclosed is a method for transmitting data for data synchronization between a server and a client. If a data synchronization session in a network is abnormally terminated, the client stores state information of data to be transmitted, which indicates states of the data at the time of the abnormal termination. The state information of the data makes it possible to resume the data transmission beginning with data items that were being transmitted at the time of the abnormal termination. Since one of the server and the client transmits only data that has not been received by the other, it is possible to decrease the time necessary to complete the data synchronization and also to reduce a wasteful, unnecessary transaction when synchronization of a large amount of data is performed.

A method and apparatus for transmitting a Byebye message when an operation of a controlled device is abnormally terminated are provided. A new field is added to discovery and Event messages defined in the UPnP standard. These messages are exchanged to allow a control point to monitor the controlled device. When the operation of the controlled device is abnormally terminated, the control point monitoring the operation of the controlled device determines whether or not the operation of the controlled device is abnormally terminated according to the presence or absence of a response to a Subscription Renewal message. The control point multicasts the Byebye message over the network instead of the controlled device abnormally terminated. It is possible to notify all control points in a network that the operation of the controlled device is abnormally terminated without increasing the load on the network and compatibility problems with existing UPnP devices.

When an IFAX processing section transmits image information using e-mail, a timer monitoring section starts the count of a timer. After starting the count, a received mail determining section determines whether or not a timeout occurs. Also, the received mail determining section determined whether an error mail of a current job or a DSN of the current job is received. In the case of the timeout, when the notification content of the error mail or the DSN is an abnormal end, a transmission selecting section instructs a FAX control section to transmit an image information file of the current job to a telephone number. Thereafter, the transmission selecting section instructs an image information managing section to erase an image information file corresponding to a file name of the current job. This makes it possible to insure a real-time property as making use of advantages of e-mail.

Method for detecting abnormal termination during model detection
The invention discloses a method for detecting abnormal termination during model detection. In the method, a counter example path is generated and recorded by constructing E', describing the E' and performing a model detection process. The counter example path provides detail execution steps for an extended finite state machine (EFSM) model under a variable configuration corresponding to the EFSM model, and the latest part of the counter example path provides information of a terminable state in a trap state. According to logic expressed by the EFSM model, whether a termination state under the variable configuration is the terminable state can be easily determined. If the termination state under the variable configuration is not the terminable state, an abnormal termination phenomenon in the terminable state is detected under the corresponding variable configuration; and if the termination state under the variable configuration is the terminable state, the abnormal termination phenomenon in the terminable state is not detected. Therefore, the detection method provided by the invention realizes the detection of the abnormal termination phenomenon.
