> 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.
