ADViewers R1-1 is now available.  This is from the release notes:

 

*************************************************

### EPICS_NTNDAViewer

* Found a serious bug in epics-pvaclient-4.3.1.jar.  A destroy() function was not being called when it should have been.

  The result was that when the NTNDArray was not reachable (i.e. IOC not running) the broadcast search requests added

  additional copies of the same PV with time.  This caused the request to grow in size until it required many

  packets.  The network was thus flooded with broadcast packets if the ImageJ plugin ran for many hours or days without

  being able to connect to the IOC.  This was sufficient to cause VME IOCs on the subnet to be 95% CPU bound just processing

  these broadcast packets.

* Fixed the logic in connectPV() when a connect attempt failed.  This was also incorrect, and could contribute to the above

  problem.

 

* Marty Kraimer fixed the problem in epics-pvaclient-4.3.2.jar, which is now included in this release of ADViewer.

 

### pvAccess jar files

* All of the other pvAccess jar files were updated to the latest versions.
