We are currently evaluating QuickOPC and unfortunately, the following issue came up once we deployed our application to a Linux host (Ubuntu Server 20.04):
This issue does not appear on a Windows host (Windows 10, >1903). We tested both, the latest stable version 5.58.257 as well as the latest preview version 5.59.0-rev13. The issue appeared with both versions. The application is currently connected to two (2) OPC UA servers and in total there are about 20 devices being served, yet only a bunch of them are being monitored. Luckily, we are still receiving subscription updates, because it seems to restore the connection pretty quickly. On the other hand though, it produces quite a lot of errors, because this issue happens a lot of times per minute.
My question now is: What does this error exactly indicate or to put it differently: What negative effects can this have to the plant? Is it highly critical? So far it seems to work, but I am really worried and would like to get this issue resolved as quickly as possible. If you need any further information, please let me know.
I saw that there are other threads referring to this issue, yet they do not seem to offer a proper solution for the problem, e.g.:
