Are there recommendations of OS setting options - Kernel

[Kim_Hakseon]

I heard that if the value of the setting below is too low, the daemon can be turned off in other DBs.

• Kernel.shmmax
• Kernel.shmall
• Kernel.shmmni

MongoDB manual doesn’t say anything about the value of the setting.
Is there any recommendation?

Hi @Kim_Hakseon,

As far as I’m aware these are not commonly tuned O/S parameters in relation to modern versions of MongoDB server.

There are a few sections in the MongoDB manual with some general configuration suggestions:

• Operations Checklist
• Production Notes
