Error description

  • Error Message: When creating a system dump, the Java VM prints a
    message like:
        The core file created by child process with pid = 3590 was
    not found. Expected to find core file with name
    "/home/jdoe/core_java.3590"
    .
    Stack Trace: N/A
    .
    Also, the JVM does not print a message like:
        JVMDUMP010I System dump written to /home/jdoe/core_java.3590
    

Local fix

  • Remove %e from core_format.
    

Problem summary

  • Core file not found if core_pattern contains %e
       Linux expands %e to the thread name, not the process name.
    This affects only Java 7 and Java 6.0.1 running on Linux.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.1 SR2 FP1
    7.0.0 SR2
    .
       The JVM dump processing has been changed to use the thread
    name instead of the process name to locate the core file.
    

Temporary fix
