Problem summary

  • ****************************************************************
    * USERS AFFECTED:  WebSphere eXtreme scale users who use the   *
    *                  eXtremeIO (XIO) transport mechanism.        *
    ****************************************************************
    * PROBLEM DESCRIPTION: Large XIO messages fail with the        *
    *                      com.ibm.ws.xsspi.xio.exception.ObjectGr *
    *                      idXIOException.                         *

    * RECOMMENDATION:                                              *
    ****************************************************************
    XIO messages larger than 64MB fail with a
    com.ibm.ws.xsspi.xio.exception.ObjectGridXIOException:
    Encountered an invalid message variant length 67437168. The max
    variant length allowed is 67108864. If large XIO messages are
    expected and normal, then a configuration option is available
    to allow for larger messages.
    

Problem conclusion

  • A code fix was made to make the XIO message limit configurable,
    if necessary, with a JVM parameter,
    com.ibm.websphere.xs.xio.message.size.limit.
    

Temporary fix
