IBM Spectrum Protect Server V8.1 Fix Pack 3 (V8.1.3) Downloads

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.
