ONTAP-32819：『Memory Leak問題in Anti-ransomware』

問題

A memory leak issue is identified in the Anti-ransomware feature.
This leak occurs on a system having one or more volumes in an anti-ransomware-enabled state.
This leak doesn't occur if the volume is in an Anti-ransomware disabled, learning (dry-run), or paused state.
A minimal amount of memory gets leaked when Anti-ransomware tries to detect the potential ransomware pattern.
The total amount of memory leaked over time can result in system disruption with a string "Process mgwd unresponsive for 210 seconds".
For the cumulative memory leak to cause the system reboot, the system should have received millions of file-create operations or many terabytes of high-entropy data via write-operations.
Post disruption, the system will reboot to a normal state and all the volumes will come online.
