How to free up RAM being used by MongoDB?
When Mongodb has ran for too long it eats up the RAM on my server thus leaving little room for other processes.
I read somewhere that restarting mongodb makes it write the data to the disk and thus free up the RAM.
I restarted it using:
sudo service mongodb restart
But that didn’t affected the RAM. Then I rebooted the server which did freed up the RAM. My question is that why restarting mongodb doesnt make it write the cache to the disk but rebooting does?
Rebooting is not a viable option always. How can I make it write out the data to disk without rebooting?
