SUSE Linux Enterprise Server 11 (x86_64)
VERSION = 11
PATCHLEVEL = 1
Recently one of our Sentinel server became very sluggish to access and its services stopped responding, we have to do a restart of the services in order to get our server back and running.
While the server was unresponsive I was able to run, free -m, and this is what the command showed me:
total used free shared buffers cached
Mem: 15956 15866 89 0 434 10051
-/+ buffers/cache: 5380 10576
Swap: 2047 46 2001
Does it mean that, used memory is 10051 and only free memory here is 89?
What is the meaning of -/+ buffers? It shows it has about 10576 memory free?
