APAR status

  • Closed as program error.

Error description

  • The SHOW THREADS command on Linux can interact with other server
    threads that are waiting for a fixed timeout by changing the
    timeout period to 4294967295 microseconds (about 1.19  hours).
    Each repeated invocation of SHOW THREADS, such as when invoked
    by the performance monitoring scripts, resets the wait period
    back to 4294967295 microseconds, resulting in threads that
    effectively hang forever.
    
    IBM Spectrum Protect Versions Affected: 8.1.2.
    

Local fix

  • Do not run the SHOW THREADS command.
