i get a lot of black zone errors for the shmpages parameter on my vps--- is this due to a lack of allocated memory- i.e. should i upgrade my memory or is this a parameter that i could request my provider to increase?
how can i reduce my shmpages usage, or see what is causing it to be so high?
This is the shared memory parameter of your VPS and your host will probably be willing to raise it for you depending on what is running on your VPS causing it to be high. Perhaps there was a misconfiguration from the start and that is something your host can check for you.
