No one has this problem? Freepbx is running on centos 6.4 64 bit. I can’t be that special? :slight_smile:

I have FreePBX Distro 4.211.64-7 (updated) installed on system with 2 GB RAM; the free -m command gives me about 538 MB free (Total: 1860 MB, Used: 1321 MB, No Swap in use at all) and I think it’s quite normal…

Linux will cache all the memory it can. If you look at what you have free after you subtract the cache you are using less then 25% of your memory.

Thanks parnassus and Tony. I just want to make sure that it’s normal. Because currently I’m noticing delay when I call via the freepbx system and this is my process of elimination to make sure that it something else that’s causing the delay not Memory or running out of resource. Many thanks again everyone.

Exactly what sort of delay are you experiencing? Without knowing that it is difficult to determine the root cause of the problem. It may not be memory related at all.
