Hi Anton,

Until now we were using the epics4.6.0 implementation in a caQtDM plugin in order to get pv’s. Now we build the plugin with epic7.0.6.
caQtDM adds a pv through a routine admonitor inside the plugin. Data are coming as before, however as soon the routine returns from the plugin, no data are coming any more (I added epicThreadSleep(5.0) in order to observe this). The plugin can be found in caQtDM
git.
What is really different from the previous version and has somebody an idea how to solve this?
There were some major changes made to the ownership rules for the client applications in pvAccess 6.0 (EPICS 7.0), and the symptoms you describe seem to match my recollection of the effects of not making appropriate changes related to that. This
page in the pvAccess documentation explained that, hopefully it will make sense.
