Error description

  • Error Message: N/A
    .
    Stack Trace: N/A
    .
    SIGPIPE kills the java process on Java6 SR9 (and SR9FP1),
    whereas previous releases this signal is ignored.
    

Local fix

Problem summary

  • The core issue is a combination of two APARs and a change
    pwgetuuid().
    APAR IZ86774 : Signal chaining does not work on Linux JDKs
    APAR IZ73232 : Signal chaining functionality issue
    Linux kernel reported against : 2.6.18-238.1.1.el5
    Upon SDK startup a call is made to pwgetuuid() before the SDK
    signal handlers are registered.  On newer versions of linux,
    getpwuid() registers a handler for SIGPIPE.  The SDK notices
    that a handler has already been registered for SIGPIPE, and as
    such, does not register the SIG_IGN handler for SIGPIPE,
    believing that the application has installed its own.
    

Problem conclusion

  • This defect will be fixed in:
    6.0.0 SR9 FP3
    6.0.1 GA FP2
    5.0.0 SR13
    .
    The JVM has been updated to register the handler for SIGPIPE
    earlier in the startup sequence to avoid this situation from
    arising.
    .
    To obtain the fix:
    Install build 20110629 or later
