----------------------------------------
Summary: Slow memory releasing while deactivation
Key: IGNITE-6758
URL: https://issues.apache.org/jira/browse/IGNITE-6758
Project: Ignite
Issue Type: Bug
Security Level: Public (Viewable by anyone)
Components: general
Affects Versions: 2.1
Reporter: Alexander Belyak
Priority: Minor
Fix For: 2.4
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, minorTop
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.
