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

> Project: Ignite
> Issue Type: Bug
> Components: persistence
> Reporter: Maxim Muzafarov
> Assignee: Maxim Muzafarov
> Priority: Major
> Fix For: 2.7

>
> 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.
