Metadata Major (page) Faults in the SAS Environment Manager

[Gooty5]

Hi - We are seeing Metadata Major (page) Faults in the SAS Environment Manager.

Description: Major Faults are page faults requiring disk activity. Possible indication of a memory constraint causing slow performance.

Metadata server (Linux OS) is running almost 23 days. Is this because of memory leak? If so, how do I resolve this alert? Really appreciate your help.

Thank You

I wrote about a similar alert another community member saw a while back with the SAS Object Spawner here. You only need to be concerned if your system is seeing major faults constantly. If you run vmstat(8) and watch the si and so columns if those are mostly low then you are likely not under memory pressure and there isn't anything to be concerned with.
