Error description

  • When using the IBM Rational Clearcase File Service (CCFS) as the
    interoperability solution to access Unix-hosted VOBS from
    Windows, an attempt to open a port that:
    1)  is in TIME_WAIT state as the result of a in-progress
    connection termination;
    2)  another process has opened for exclusive access
    
    Will result in a "Permission denied" error. This is a
    Windows-specific behavior. In a Unix environment, those
    conditions will cause an "Address already in use" error, and the
    ccfs code will simply move to the next port and try again.
    

Local fix

  • The current workaround is to not use CCFS.
