Hola Todos!


For a long time (I don't know if ever) sbbs has been using a lot of memory. I don't know if it's normal, but it doesn't seem like it to me.

I have a virtual machine on a friend's servers who kindly lends it to me :)

The virtual machine, virtualized with xen, has 1.25G of memory and an AMD Opteron (tm) Processor 4280.

Here you have a top to see the memory usage of sbbs:

It is normal?

If you run the web server, yes. The main thing is the RAM usage settles and does increase continually (e.g. a memory leak).

How can it be fixed? Rebooting can be fixed? Because it doesn't work for me. When I reboot, in a short time the memory goes to 60-80%

Thanks DM.

Add more RAM. Or try simplifying your web UI or maybe use a different web UI. If it's not continually increasing over time, then it's not a leak. It may just be an inefficient use of memory by the web UI you're using.

I am using the webv4 without any changes.

More ram is complicated. My friend just increased me a little bit of ram, from 1G to 1.25G yesterday, and it seems that now it uses more percentage of ram. Now is in 85% :(

So maybe try the legacy/runemaster web UI instead.

You could also try lowering your JavaScriptMaxBytes value in your ctrl/sbbs.ini file.

according to your tear line, you are on linux... remember that linux uses memory a lot differently than other OSes... memory is faster so things are cached into memory for speed... linux will use as much available memory as
necessary for best operation... note the swap usage in the below... then also note the memory used for cache ;)

I'm not doing any FTN feeds at the moment, and am running a few
containers on the BBS box, here's my stats.

total used free shared buff/cache available
Mem: 2035332 582052 181696 1416 1271584 1278400

49887efc63df irc 0.03% 11.27MiB / 1.941GiB 0.57%

That's after about a week running since I last updated. 2gb, 2vcpu
Ubuntu vps on Digital Ocean. I really don't have any users to speak of
and modding is barely started.

I have web and irc separated in order to isolate the usage. Looks like
total memory usage on my system is 582gb. The main sbbs terminal and
services along with ecweb are the biggest memory users.

Been thinking of breaking nntp service off into a separate container as
well, since irc and nntp are really the only longer lived connections
other than terminal connections themselves.
