Abstract
File system errors are handled and computing systems are recovered by, responsive to receiving a page buffer request, initializing a sleep timer according to a detection interval value plus a 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. This process is then optionally repeated for additional processes, threads, application programs, daemons, tasks or combinations thereof which are waiting for availability of the requested page buffer, optionally randomizing the detection interval value in order to avoid an instantaneous recovery from the error.
