APAR status

  • Closed as program error.

Error description

  • From IIB 10.0.0.12, on startup on UNIX and Linux platforms, the
    integration node processes no longer inherit undesired file
    descriptors from child processes upon start or restart after
    failure. See APAR IT23390 for details. It implements this by
    calling fcntl() on each owned file descriptor and setting the
    FD_CLOEXEC (close-on-exec) flag. However a bad file descriptor
    causes the following unhandled exception:
    
    (Msg 2/2) BIP3150S: A socket error occurred. Operation:
    ::fcntl(F_SETFD). Error Code: 9. Error Text: Bad file
    descriptor.
    (Msg 1/2) BIP2121E: The thread bootstrap code caught an
    unhandled exception on thread number '12345' with name ''.

    PROBLEM DESCRIPTION:
    From IIB 10.0.0.12, on startup on UNIX and Linux platforms, the
    integration node processes no longer inherit undesired file
    descriptors from child processes upon start or restart after
    failure. See APAR IT23390 for details. It implements this by
    calling fcntl() on each owned file descriptor and setting the
    FD_CLOEXEC (close-on-exec) flag. However a bad file descriptor
    causes the following unhandled exception to be logged in the
    system log:
    
    (Msg 2/2) BIP3150S: A socket error occurred. Operation:
    ::fcntl(F_SETFD). Error Code: 9. Error Text: Bad file
    descriptor.
    (Msg 1/2) BIP2121E: The thread bootstrap code caught an
    unhandled exception on thread number '12345' with name ''.
    
    This may cause the integration node process to become
    unresponsive to certain requests, for instance shutdown.
    

Problem conclusion

  • The product no longer throws an exception on startup if the
    fcntl() system call fails, but an error is logged if the return
    code from the call is anything other than success or bad file
    descriptor.
