[jira] [Commented] (PLC4X-172) ADS driver does not shutdown all
threads (hangs) after closing connection
[ https://issues.apache.org/jira/browse/PLC4X-172?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17029904#comment-17029904 ]
Christofer Dutz commented on PLC4X-172:
---------------------------------------
Are you using the new drivers? We recently did a huge refactoring to the drivers in the last two months. As far as I know we aren't completely finished with the ads driver and the new version is still in the sandbox.
