I'm running version 3.4 of mongo on a windows server 2012 R2 using the default storage engine (Wired Tiger). The mongod is running as a Windows Service.
Unfortunatlly the service crushes from time to time with a "out of memory" error. this is from the mongolog:

2017-05-14T22:34:15.902+0000 F - [ftdc] out of memory.
After some research, people suggest to limit the memory usage:
- Using WSRM (https://www.captaincodeman.com/2011/02/27/limit-mongodb-memory-use-windows) Unfortunatlly this feature is currently not available on windows 2012 server.
- Running the mongod inside a special container or a virtual machine (Heper-V /Vmware...) in order to limit its resources - I guess that the probelm will return in the Virtual machine - the process will be out of memory there.
- Limiting the WiredTiger cache size (https://docs.mongodb.com/manual/faq/storage/#to-what-size-should-i-set-the-wiredtiger-cache) - I already decreased the size to be 1 Gb and it doesn't help. Besides it, it only limits the cache, the mongod process itself can the RAM in other way.
-I saw that in the linux version there are "unlimit" flags that can be set MongoDB: out of memory
-Is there similar configurations in windows versions?
-Is increasing the page file size can help?
-Other suggestions?
Thanks!
