An issue has been reported with the Universal Driver 4.7 where, under certain circumstances, the UD (Universal Driver) Manager does not display active workstations and locked records. The issue is pretty obvious when it occurs because the list of connected workstations and locked records will either display empty or incomplete. The screen shot in this posting shows the UD Manager whilst the issue is occurring. Please note that there are no error messages displayed by OpenInsight nor the Universal Driver and connected workstations function normally.
The missing workstations and locked records can occur when the UD Manager encounters more than 16 consecutive disconnected sessions. The UD Manager will stop checking for new sessions after it reaches the limit. The disconnected sessions are a normal part of the Linear Hash services operation as clients connect and disconnect from the Linear Hash service.
To resolve the problem an updated version of the UD Manager 4.7 has been released and you can get more details about the issue and installing the update at http://www.revelation.com/o4wtrs/KB_Articles/KB1019.htm.
