Hello, Ilya,Attached are two thread dumps, the second is taken 13 minutes after thefirst one: threaddump.txt <http://apache-ignite-users.70518.x6.nabble.com/file/t2262/threaddump.txt> , threaddump2.txt <http://apache-ignite-users.70518.x6.nabble.com/file/t2262/threaddump2.txt> .The hanging occurs in the main thread (in fact the same output is for threaddump taken after 8 hours):The differences between two thread dumps are minor, one of them is asfollows:in the first thread dumpin the secondWhat concerns a reproducer project, this is not an easy task, because it isdifficult to understand which factors may be treated as significant. Ourinitial project is in general stable, the matter is that we have dozens of buildson our build server per each day and only some of these builds fail. It is very difficult tocatch this situation, I have had to launch 5 builds one after another beforethis situation really occured. And it may be that this situation requireslaunching very specific containers in Docker each at very specific time. Andwe cannot share our original project, all I can do is to give you thoseparts of the code that deal with Ignite. For example, the full code of startmethod from DbManager is as follows:And we have logs for all containers of our app including those for Igniteserver nodes, if you like I can provide them.Thank you very much for your help in advance.My best regards,Ilya
