+Subject: [PATCH] Fixing for new free output.
+
+The output of free doesn't anymore contain the "buffers/cache"
+line breaking the check_memory plugin. The attached patch uses
+instead the new "available" column to calculate the free memory
+as it seems to be a better estimation of free (usable) memory.
