I have a Mango 2.8.8 instance with 310 data points. The hardware is 2.0GHz + 2 core + 4GB RAM Virtual machine on Windows server 2016.
I restarted the Mango because a Windows and Java update. After the update and restart, I started the Mango, but it won't start properly. After the start process, I can log in, so the Spring and the website is working correctly.
After the log in if I click on the datasource icon, it shows an empty list of datasources. The Graphical views icon won't load the webpage, it just starts to load. In the SQL webpage, the "get tables" start the process and it will never end. The main problem is the settings webpage also not loading, so I cannot set the thread pool values.
I had lots of "thread pool is full" log messages in the past without any major problems, but I did not touch the thread pool sizes in the settings (1, high=100, med=2, low=2).
I think the problem is with the H2 database, because the webpages are rendering. Maybe it become corrupt...?
Another question: how to stop the Mango correctly? I pressed the ctrl+c in the console and it shutted down in a minute correclty.
