Hi Sriram,

I raised a call with Oracle requesting more details on the bug number you
quoted (4008013), however they have told me that this bug does not relate to

I'm quite interested in this problem you describe as we use (and reply on)
LOG_PARALLELISM in our HP-UX environment.

Do you have any other information I can give Oracle that may help them locate
the details? Maybe a TAR number?
