The -1967390689 points to a problem attempting to log to a buffer that is full. There are couple of things that can be done to address the problem. First, you can try increasing the queue size in the Tag Configuration Editor (Configure>>Engine>>Server).Secondly,in the Logos.ini file (Win9x: c:\windows\system\logos.ini, WinNT/2k: c:\winnt\system32\logos.ini, look for
[Citadel] MaxQueueSize=### in points LogPeriod=### in milliseconds
MaxQueueSize is the number of times a single point can change before DSC or Lookout finishes configuring all points for logging. The default is 500. Setting this to something like 5000 will probably give DSC enough time to configure points.
LogPeriod is how often the logging buffer is flushed to the datab ase. The default is 200. If you have a lot of points, this can be very slow, since DSC needs to get the timestamp from each point before logging to the database. Setting this to something like 2000 (2 seconds) or more will free up the processor a bit, although HyperTrends will update considerably less often, but they are probably doing that anyway if the logging buffer is filled up.
Lastly, you may try upgrading to the newest release of Logos. The Logos 4.3 installer can be downloaded from ftp://ftp.ni.com/support/lookout/logos/.
