We have a manager driver which is able to subscribe to cells in tables from different elements and display the values in a table within the manager.
The manager subscribes to different tables on that same element and sometimes values are not received or it keeps displaying the same value for hours/days even restarting the manager and re-creating the subscriptions does not solve the issue right away.
The trending graph at the bottom is from the manager which has the subscriptions. The graph on top is from the source element.
After killing the subscriptions and re-adding them the graphs start to match up again.
The issue is that some subscriptions stop updating/receiving changes but others within the same element continue working?
What could be causing this?
Dataminer 10.2.4.0-11608
Number of subscriptions ~4500
This issue will probably require a more in depth investigation
I would suggest to take the following logging while the issue occurs:
-LogCollector package of DMA where the remote element is hosted with the SLProtocol memory dump of the remote element + SLNet memory dump included
-LogCollector package of the manager element DMA with SLProtocol memory dump of the manager element and also including the SLNet memory dump
The suspiscion is that for some reason the subscription get lost and doesn't get reinitiated, i can also imagine DMA restarts, disconnects, RTEs might come into play here
Issue as of today was because on an issue in the driver and the way the subscriptions were handle when dealing with the primary keys of the source elements.
