Linux VPS CPU usage, help.

DukeeH · Apr 15, 2016

Hello, id like some help, i've got a VPS about 2 months ago, made some changes on the server and it got to 130 players online really fast, but i'm having problems with some ppl complaining of lag, and when i when to check the usages (top command on ssh) it showed me this:

2537 root 20 0 1269m 1.1g 8180 S 84.9 28.9 57:09.88 theforgottenserver
(84% cpu usage, it goes from 80% to 96%, even 98 or 99 sometimes)

It's not that much (130 players) plus the map is small, but the only thing i have is attackspeed (about 150~ ms) and talking teleports (2s), is it right or there's some bug on source/scripts?

I would reccomend you deactivate the talking teleports and check cpu usage, if not, there may be a bug in scripts, try disabling npcs and check. If not, disable customised scripts. If then the issue continues it may be distro issue.
It would be a good idea to tell us the distro you're using.

DukeeH · Apr 25, 2016

Will try to disable talking tps, it's a bit hard because the server is on. But sometimes the cpu usage goes more than 100%.
Still need help.

Checked both consoles (2 servers, different hosts) for a few minutes, the only errors I saw were this:

Code:

[Error - Action Interface]
data/actions/scripts/castlewar1.lua:onUse
Description:
(luaGetThingFromPosition) Tile not found

[Error - Action Interface]
data/actions/scripts/tools/rope.lua:onUse
Description:
(luaGetThingFromPosition) Tile not found

The first one was spammed.

Scripts:

lib/050-function.lua (function used on the action)

Code:

function expulsar(guild, fromx, tox, fromy, toy, z, outpos)
    for _x = fromx, tox do
        for _y = fromy, toy do
            local player = getThingFromPos({x = _x, y = _y, z = z, stackpos = 253}).uid
            if (isPlayer(player) == true) then
                if (getPlayerGuildId(player) ~= guild) then
                    doTeleportThing(player, outpos, false)

More info: (SCREENSHOT top command + online players) (First server goes up to 94% with this amount online)

I really should try disabling some globalevents to see if it will work. Will try to do it today, it's a bit hard with server online.

Maybe try disabling Castlewar, which is the one that spammed errors.

It's only spammed sometimes, not related to the cpu usage that occurs almost everytime.

GoalTV · May 20, 2016

If you haven't solve this yet.

Try disable script by script and see what could be causing the lag.

"But sometimes the cpu usage goes more than 100%."
you can't host OTS on a quantum computer derp

upgrade your vps xD 4gb ram is low..
