Hello! I'm not really sure, maybe it is because nodes tried to enter PME when they were already unable to communicate and therefore not all cache operations were completed.
Anyway, since your logs don't start from beginning, it's impossible to know if there were any other clues. Currently there are none. Please also consider https://issues.apache.org/jira/browse/IGNITE-11365 Regards, -- Ilya Kasnacheev чт, 26 сент. 2019 г. в 19:11, Abhishek Gupta (BLOOMBERG/ 731 LEX) < agupta...@bloomberg.net>: > Thanks for the response Ilya. > So from a sequence of events perspective, first the logs show "Partition > states validation has failed for group" for many minutes.
