ZookeeperClusterNode memory leak(potential)

Hi team,

About 50 nodes (including client nodes) were discovered by zookeeper.

After running for about 2 days, you will find that the number of ZookeeperClusterNode instances increases significantly (about 1.6 million). After running for a longer time, it may cause memory overflow.

What version of Ignite are you using?

Hello!

If you can reproduce this issue reliably, can you provide logs and heap dumps from one of the runs?

Regards,
