> We need remove uneeded {{ZkPinger}} from our codebase, introduced in
> [IGNITE-9683|https://issues.apache.org/jira/browse/IGNITE-9683].
> This pinger was introduced to solve issues with server nodes segmentation
> when cluster is deactivated. The main reason of that is the strange all
> thread freeze when huge amount of memory is deallocated with
> {{Unsafe.freeMemory}}, such freeze can last for a minute and more. So this
> pinger doesn't solve problem at all and this is proved. The working solution
> to this problem is introduced in
> [IGNITE-9658|https://issues.apache.org/jira/browse/IGNITE-9658]
> So we should remove this code from our codebase.
