We have a 3 node cluster with persistence enabled, sometimes I see below error happening.

I had to restart all the nodes to recover from this error.

Also I have configured health check to identify this situation but I was not able to determine with the below check. Am I doing something wrong? private Collection<Integer> getForLostPartitions(){ Collection<Integer> lostPartitions = ignite.cache(CacheIdentifiers.USER_IGNITE_CACHE_PRIMARY.toString()).lostPartitions(); return lostPartitions; } if(checkForLostPartitions()){ Health.down().withDetail("Lost Partitions",getForLostPartitions().size()).withDetail("Partitions Lost ", getForLostPartitions().toArray()).build(); } Any help would be appreciated.
