Responsive to detecting a failure in a computer system determined by receiving a trap from at least one component integrated in the computer system, a notification to a recipient may be transmitted. A service ticket is created associated with the failure. One or more other problem events occurring during the failure is detected and an indication that the other problem events occurred during the failure is recorded. Notifying the recipient during the failure, of the one or more other problem events, is prevented. Responsive to detecting a resolution of the failure, the service ticket is updated with the other problem events with the indication that the other problem event occurred during the failure.

Detecting stalling of a software process in a computer system includes receiving identification of a work process thread group, including a work process thread, for a task. The task is marked as running responsive to detecting whether there is a state change for the work process thread and is marked as stalled responsive to detecting an absence of the state change for a first predefined amount of time. The work process is marked as stalled responsive to detecting an absence of a predetermined signal from the work process for a second predefined amount of time. An API gets stack traces for the work process thread via calls. Instances of a hash are calculated for each of the stack traces. Respective instances of the hash calculated at least the first amount of time apart are compared for detecting whether there is a state change for the work process thread.

Technology for stall detection

A method, system and computer program product for determining a relative priority for a job. A 'policy' is selected based on the job itself and the reason that the job is being executed, where the policy includes a priority range for the job and for an application. A priority for the job that is within the priority range of the job as established by the selected policy is determined based on environmental and context considerations. This job priority is then adjusted based on the priority of the application (within the priority range as established by the policy) becoming the job's final priority. By formulating a priority that more accurately reflects the true priority or importance of the job by taking into consideration the environmental and context considerations, job managers will now be able to process these jobs in a more efficient manner.

Determining a relative priority for a job using context and environmental considerations

Detecting stalling of a software process in a computer system includes receiving identification of a task thread group executing in a work process executing on a computer system. The task thread group includes one or more threads and the receiving includes receiving identification of the one or more threads by a control process executing on a computer system. The detecting includes detecting whether there is a thread state change for the task thread group, marking the task as running responsive to detecting a thread state change for the task thread group, marking the task as stalled responsive to detecting an absence of a thread state change for at least a predefined amount of time, and marking the work process as stalled responsive detecting an absence of a predetermined signal from the work process for at least a predefined amount of time.

A method, system and computer program product for reducing the failure of processes. After a job is received, a determination is made as whether the received job is a 'short-lived job' or a 'long-lived job.' A short-lived job refers to a job who accomplishes a given task in less than a threshold period of time. A long-lived job refers to a job who accomplishes a given task in greater than a threshold period of time. For an identified long-lived job, the long-lived job is executed on a single process apart from other processes; whereas, the short-lived job is executed on at least one process separate from the processes executing long-lived jobs. As a result of executing the long-lived jobs on separate processes from the short-lived jobs, the likelihood of having a process fail is lessened since the duration of time that the process is running will be lessened.
