Hi,

On a Squid server I'm seeing how the buffer mem usage is steadily growing.

I'm running out of free memory.

I'm not familiar with how the Linux kernel manages memory, so I don't know if the "buff/cache" memory is easily reusable by user processes.
In other words, should I worry or not if the value of "free" (in top) drops that much?

I not sure how I'm supposed to interpret the output of the ps commands above.
For example, the sum of %MEM is usually between 5 and 10%. Shouldn't this mean that the overall system is not requiring that much RAM?

Also, my squid settings are quite modest in that I have this in the conf file:
