this morgning I encountered an oom situation in my brandnew TS-473A. I would like to get the root cause of the issue if possible. So if you have any ideas, let me know.
It is a TS-473A with 40G of RAm, QuTS hero 5.0.0.1856 (latest).
I have only Virtualization Station installed, doing malware scan and sharing folders to Windows. As virtualization I have a single VM up and running which has 4GB of configured memory.
Two RAID1 ZFS volumes (2TB and 6TB) and a SSD cache from my two m2-SSDs. One share is configured to do compression and deduplication.
This morning I got an alert from my NAS about having to few memory ressources and Virtualization Station was stopped and some pyhton task was killed:
