APAR status

  • Closed as program error.

Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    

Local fix

  • The number of garbage collector threads can be manually set by
    the user using the "-Xgcthreads" option. For example, to set the
    number of garbage collector threads to 3 use "-Xgcthreads3"
    

Problem summary

  • The number of garbage collector threads, reported as "gcthreads"
    in the verbosegc log, is the system processor count instead of
    the number of processors available to the java process (e.g.
    when process is run with limited processors using taskset on
    linux).
    

Problem conclusion

  • The number of garbage collector threads is now set to the number
    of available processors.
