memory use and performance?
i have a linux box with rh7.3, ensim, and about 20 accounts...
i've been having a series of problems where available memory shrinks to the point where linux starts killing processes...first exhibiting as a slow-down in http, email, etc...and then eventually not responding to ssh or emial, tho the box always remains pingable.
what can cause this?
can anyone point me towards the likely suspects or logs to check?
cheers
