Hi, I have had a server setup for quite some time now, running 5.0.5, and I was recently looking into why I was running out of memory.

 

I have 6 gb of ram (2 gb sticks x 3) however when I invoke a free command in terminal 1772208 kb total (1.7gb). If I also run the command cat /proc/meminfo I get the same values (1.7gb total).

 

The strange thing, however, is when I  click system info in the webgui it displays that I have 6gb of ram. Sorry if this is a simple issue. My linux skills are only so so.

 

Thanks so much

You are most certainly not running out of total memory but out of low memory... That cannot be fixed by adding more memory. The fix would be to use the 64 bit version when it is stable..

 

I do however wonder why you are getting OOM (out of memory) errors.. Unraid performs perfectly, even full with plugins with 4gigs.. What are you running ?

Why do you suspect you are running out of memory?

 

Please post the output of "free -ml".

 

I currently have no apps installed so I do not know why I would be getting OOM errors. It should be noted that this morning I updated to the 64 bit beta to see if this affected the issue, currently not running any virtual machines or apps.

 

root@Tower:~# free -ml

            total      used      free    shared    buffers    cached

Mem:          1732      1716        15          0        99      1309

Low:          1732      1716        15

High:            0          0          0

 

Attach a syslog.

So after a restart it seems I no longer have a memory leak, as far as I can tell. I still only have 1.7gb of low memory however. Since I am no running the beta 64 bit (so now this tread is in the wrong section but the problem was still prevalent in 5.0.5) shouldn't I have more low memory? I have also attached the system log if that helps.

 

Thanks so much for every ones help

Have you booted with Xen active?    If so then the syslinux.cfg file for beta 3 is limiting Dom0 to using 2GB of RAM.  I believe that  beta 4 is removing this limit.

Alright, since I think this is becoming a Xen issue relating to the Dom0 limit, I'm going to move my questions into the appropriate forum.

 

Thanks so much
