SOLUTION:

To solve the issue, use the following alternatives:

The anti-virus scanner had additional processes running during the time-frame.  Disabling the anti-virus scanner can resolve this issue

1.  Disable Anti-Virus

2.  Resolve the OS level Anti-Virus privilege issue(s) if there are any

3.  Re-enable Anti-Virus

Note:  There are no OS level permission issue on the directory and even changing permissions to 770 or 777 doesn't resolve the issue.  This is the Anti-Virus which is preventing from writing the ADR logs

To stop McAffe & it's Scanner, do the following:

/etc/init.d/cma stop
/etc/init.d/nails stop
