In 2.7.6 I did not observe the behavior you described. There were some issues with partition loss policies in earlier versions -- https://issues.apache.org/jira/browse/IGNITE-10043 -- that were subsequently fixed.
What version of Ignite are you using? Can you attach a reproducer project? -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
