Bug Fixes
Bug Fix Description
Reference #
ThingWorx Analytics Server: Periodic application restart is required or the server becomes unresponsive
In the Results microserver, certain results files are not being closed after reading or writing to them. Eventually the system reaches its resource limit for open files and begins to generate errors. A server restart becomes necessary. This issue has been resolved so that results files are closed after reading or writing.

Known Issues
Known Issue Description
Reference #
ThingWorx Analytics Server: Two-at-a-time Signals request does not return MI for all field combinations
When running a request for Signals, and specifying maxAtATime = 2, Mutual Information (MI), in relation to the goal, is not returned for all field combinations as expected. Instead, individual (one-at-a-time) MI scores are returned for all fields and then are filtered down to the top 25% most relevant fields. Two-at-a-time signals are calculated only for those fields. There is currently no way to modify this filtering behavior.

Analytics Manager: An existing simulation event fails if it is triggered after server restart
Analysis agents must be restarted after a ThingWorx server restart. Without restart of the agent, any new simulation jobs will fail to execute.
Analytics Manager: A time window event does not work for non-time series models uploaded using the Analytics Server Connector when all properties of the thing, including the key field are mapped
AM-1289
Analytics Manager: The Replay progress bar does not update as expected
When a replay event is executed, the on-screen progress bar does not update as the replay event progresses. The issue is related only to the user interface (UI), and the actual execution of the replay is not affected. As a work around, refresh the browser or navigate to another tab and then return to the Replay tab. The progress bar will update. This UI issue will be resolved in a future release.
AM-1345
ThingWorx Analytics Server: The reported version number is an internal versioning number
The Version Info service currently returns a version number that indicates both the external version and the internal build version, but not a path release version. Possible changes in version information are under consideration for a future enhancement.
TA-1217
Analytics Builder: Filtering on list pages does not work as expected
When filtering is applied to a list page with multiple pages (such as the Models list page), the filtered results are not aggregated for display on a single page. Instead, the filtered results remain on their original pages and multiple pages must be clicked through to find all the filtered results.
To improve handling of list page displays, a configurable parameter has been added to set the number of table items that can be displayed per page. A more permanent resolution for the filtering with pagination issue will be provided in a future release.
TA-1596
Analytics Builder: Screens do not load properly in IE 11
The View Datasets and View Models screens do not load properly in the IE 11 browser for the support Windows operating systems. This issue will be resolved in a future release. To avoid the issue, use another browser, such as Chrome, Firefox, or Safari.

Analytics Builder and Analytics Manager: Sizing of pop-up windows is distorted
When the Analytics Extension is deployed on the 8.3.1 version of ThingWorx platform, the display of some pop-up windows might look compressed in Analytics Builder and Analytics Manager. In some cases, scroll bars will allow you to view truncated fields. However, the best work around for the issue is to maximize your browser view so that the pop-up windows can display fully. This issue will be resolved in a future release.
