>
> Create an ignite client (in client mode false) and put some data (10k 
> entries/values) to it with very small expiration time (~20s) and TTL enabled.
>  Each time the thread is running it'll remove all the entries that expired, 
> but after few attempts this thread is not removing all the expired entries, 
> some of them are staying in memory and are not removed by this thread 
> execution.
>  That means we got some expired data in memory, and it's something we want to 
> avoid.
> Please can you confirm that is a real issue or just misuse/configuration of 
> my test?
> Thanks for your feedback.
>  
> To reproduce:
> Git repo: [https://github.com/panes/ignite-sample]
> Run MyIgniteLoadRunnerTest.run() to reproduce the issue described on top.
> (Global setup: Writing 10k entries of 64octets each with TTL 10s)
