Ragdoll/crazy physics server crashes

[mescom]

Hi,

I've been struggling with the following server crashes for the last week:

I followed the instructions I found on a TTT topic (link: [url]http://www.zombiemaster.org/smf/index.php?topic=13234.0[/url] ), quote:

I currently have three commands to prevent the ragdolls from crashing and one script. The script let alone should do the job but all this it isn't normal behavior at all.

Commands I have running:

sv_removecrazyphysics 0
cl_ragdoll_collide 0
ttt_ragdoll_collide 0

The script I have on the server currently(I have tried at least 3 to 4 versions of this script):

local freezespeed = 300
local removespeed = 3000

function corpse_identify(corpse)
        if corpse then
                local ply = player.GetByUniqueID(corpse.uqid)
                ply:SetNWBool("body_found", true)
                CORPSE.SetFound(corpse, true)
        end
end

hook.Add("Think","AMB_CrashCatcher",function()
        for k, ent in pairs(ents.FindByClass("prop_ragdoll")) do

The error I get when the server crashes:

Now, after having said suggested changes, both settings & addon from the quote/topic above, crashes has decreased, but I'm getting these now, and it sounds like this and the entire thing is more your domain than scripters, and I failed to find much data at all on google, so I figured I'd report it, hopefully/probably this is a dupe of an existing report, but better reporting twice, or a hundred times than never.

Holy shit did this genuinely never get fixed

[c👌de_g🎷]

Yeah, I tried to revise the script to just remove it if it's repetitively frozen, but no script can fix the issue. I've tried so many different methods and there's no sure-fire way of solving the issue.

[editline]8th March 2014[/editline]

There's just nothing anyone can do until Garry/_Killburn can fix the issue.

It's becoming so common I'm suspecting possible exploit to provoke it might exist, any way to give this some priority?

[c👌de_g🎷]

Garry isn't working on GMod at the moment, so no way of seeing this fixed soon.

[mescom]

Well what to do then? Checking my console logs I've had 4 crashes the last 3 hours on random maps (ran a quick log search now for map name prior to crash, it has no pattern to be cause.)

And for instance, entire yesterday went by with not one crash, today we had 8 where 4 of them was within the past 3 hours.

It's too weird to not have some kind of pattern, whether be intentional or unintentional exploit it must be bound to what some player is doing. Any tips is appreciated as I don't really see a future hosting servers on an unstable game. Hurts my community.

[c👌de_g🎷]

There really isn't anything you can do until it's fixed.

Garry's GMod touchup skills are getting rusty.

I see what you did there.

Any chance to get an official response to this? Because I wont keep the servers up if they crash randomly.

[c👌de_g🎷]

This problem has come up many times before. No response from Garry either since he's not even working on GMod atm.

This is unfixable due to the fact that we don't have access to vphysics.dll sources.

Probably licensing issues or something.
