----------------------------------------------------------------

ok, here are final results with 100 iterations activate/deactivate scenario:

without fix, total process memory is slowly increasing approx each 20 iterations:
{noformat}
10298776
...
10283356
10284384
...
10286432
{noformat}

with fix, total process memory is changed a little first few runs, than remains constant all
90+ iterations
{noformat}
14501520
10099096
10232216
10232216
10297752
...
10297752
{noformat}

so, it seems, that this scenario also shows memory leak fixed, [~Mmuzaf], [~agoncharuk] please
confirm

> Calling multiple time cluster (with enabled persistence and started client nodes) activation
{{ig3CB.cluster().active(true);}} leads to non-heap memory leak.
> Line {{org/apache/ignite/internal/pagemem/impl/PageMemoryNoStoreImpl.java:234}} looks
suspicious because of in case method {{org.apache.ignite.internal.pagemem.impl.PageMemoryNoStoreImpl#start}}
callled multi times (e.g. activate(true) called multi times) we lost info about allocated
regions.
