APAR status

  • Closed as program error.

Error description

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

Local fix

  • No known workaround.
    

Problem summary

  • Java generates an excessive number of signals gathering native
    stacks for javacore files
    

Problem conclusion

  • Signal handling is more robust in Linux kernel releases 3.0 and
    later. In those Linux kernels, Java no longer needs to queue so
    many signals to ensure that native stacks are collected in a
    timely manner.
    .
    This APAR will be fixed in the following Java Releases:
       8    SR3 FP10  (8.0.3.10)
    .
