TTank Engine sometimes stops recording

Tech Note: TN0950
Product: OpenEx
Version: 2.20
Date Added: 2014-12-23


On rare occasions, TTank engine stops storing data in OpenEx v2.20 on 64-bit operating systems. This typically occurs with very high channel count or high event count recordings.

In the Workbench Status window below, notice the Event Rate and Data Rate indicate a problem. Workbench continues to run and display data, but the data is no longer saved to disk.

Block data stored before the interruption can be recovered with the TankRestore utility. For a link to TankRestore and instructions on using this tool see Tech Note #0935.


Upgrade to the latest version of OpenEx. This was resolved in v2.20.1.
