> If we use persistence in tests and do not explicitly set the max size of a data region, by default it will be 20% of available RAM on a host. This can lead to memory over-usage and sometimes JVMs, where such tests are running, will be killed by Linux OOM killer.
> We should find all tests where data region max size has forgotten and set this value explicitly to minimal possible value.
