----------------------------------------
Re-run seems that test was fixed, so I set PA status again. WIll take a look
> Optimize memory usage of data regions in tests

> Project: Ignite
> Issue Type: Bug
> Components: cache
> Affects Versions: 2.6
> Reporter: Pavel Kovalenko

> Fix For: 2.7

>
> 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.
