I'm using 2.x version of Mango SCADA with enterprise license + DGLux 2.5.
The system has 240 Modbus I/P sources created, in two different groups of 120 each. The first group has 348 points per source and a polling frequency of 24 hours, and the second one has 62 points per source and a polling frequency of 5 minutes. 120 devices with 120 different IP addresses are connected to Mango and each device has one source from both groups polling it for data. 60 devices are connected to the internet with cable and the other 60 are connected with 2G GPRS. Along with that, I have one Meta source with 120 points that calculate something every minute for each of those devices using their data. That's the setup.
Here's the problem. every now and then some Mango source stops poling some of these devices (not discriminating them by their internet connection type) even though they are available and responsive. If I turn off that source and turn it on again, it'll start working immediately. It also happens for Meta points, some of those points would just stop doing new calculations. If I turn the Meta source off and on, they'll start working orderly.
