> It take about 1 minutes to fill each page by 0 and release it to page pool in PageMemoryImpl.ClearSegmentRunnable()
from GridCacheDatabaseSharedManager.onCacheGroupsStopped(). When we have 100+M pages in hundred
of Gb of pageCache in take quite long to GridUnsafe.setMemory to 0 and in logs we get lot
of "Failed to wait for partition map exchange [topVer=AffinityTopologyVersion [topVer=56,
> Ver=1], node=3676f020-0bf0-4145-861e-689c96d7e853]. Dumping pending objects that might
be the cause: "<no cause here> without any cause and progress indicator. So full grid
reboot take longer downtime with unnecessary warnings.
