Resolution of system hang due to filesystem corruption

A system for handling and recovering from file system errors in a computing system comprising:

• a processor for performing a logical process;
• at least one computer-readable storage memory device;
• a flag disposed in the at least one computer-readable storage memory device to enable handling potential hang up scenarios;
• a hang detection interval value disposed in the at least one computer-readable storage memory device;
• a hang resolution range value disposed in the at least one computer-readable storage memory device;
• and
• one or more program instructions disposed in the computer-readable storage memory device for causing the processor to perform operations comprising:
• responsive to receiving a page buffer request, and responsive to the enablement flag being enabled, initializing a sleep timer according to the detection interval value plus the hang resolution range value;
• responsive to the timer expiring, detecting that a process, thread, application program, daemon, or task is waiting on availability of the requested page buffer;
• and
• responsive to the detection, quarantining metadata associated with the requested page buffer, failing the page buffer request and releasing one or more locks on the requested page buffer;
• wherein the at least one computer-readable storage memory device is not a transitory signal per se.

A computer program product for handling and recovering from file system errors in a computing system comprising:

• a flag to enable handling potential hang up scenarios;
• a hang detection interval value;
• a hang resolution range value;
• first program instructions for, responsive to receiving a page buffer request, and responsive to the enablement flag being enabled, initializing a sleep timer according to the detection interval value plus the hang resolution range value;
• second program instructions for, responsive to the timer expiring, detecting that a process, thread, application program, daemon, or task is waiting on availability of the requested page buffer;
• and
• third program instructions for, responsive to the detection, quarantining metadata by the processor associated with the requested page buffer, failing the page buffer request and releasing one or more locks on the requested page buffer;
• wherein the a enablement flag, the hang detection interval value, the hang resolution range value, and the first, second and third program instructions are stored by at least one computer-readable storage memory device which is not a transitory signal per se.
