I create small reproducer project/ It is available on: https://drive.google.com/file/d/1A2_i1YBI7OGtJM0b8bxuIJrTI61ZQXoR/view?usp=sharing
Thera are project, and some logs and dumps in archive. There is only one DemoTest.java to run to reproduce. test run 3 ignite nodes with configuration very similar to our real project without any logic or additional services. IMPORTANT. As I investigate during reproduction, evrething works fine when I run test on local drive (SSD in case of my laptop), but if I copy project to external HDD mounted over USB3.0, problem present. So it may be race caused by condition on slow IO. Initialy I got problem when I build my project on external drive. Andrey.
