Grey 'Collecting data...' while debugging
Answered
I'm debugging a remote server. Can successfully connect to the server — "Connected to the target VM, address: '***', transport: 'socket'" — but often if debugger reached a breakpoint, it hangs with endless 'Collecting data...' and it may continue for a long time.
If I step over/resume after that, I can't even reach next row/line/breakpoint
Tried it at IDEA 15.0.6 and IDEA 17.2.1

It may be specific to the Java version you are using, to the code you are debugging, to the container, debug options, breakpoint type, etc.
