Server crashing randomly

[Sidewaykill]

Our server keeps crashing, and it throws this error, on certain maps:
Crazy physics on [427][prop_physics] [Ang:-1.#IND00,1.#QNAN0,180.000000] [Pos:-1.#IND00,-1.#IND00,1.#QNAN0] - removing

Then it basically restarts, but doesn't crash SRCDS. What is going on, and how can I fix it?

[Lolcats]

If it's crashing on startup, the map might have a prop that's' conflicting with the Crazy physics detector. You COULD go into the map and make sure all the props are looking right and tidy. Otherwise if it's when people are playing, someone might be crashing your server.

[Sidewaykill]

It's not on startup. It happens randomly, while the server has players on it.

[NiandraLades]

Also having this issue, we'll crash once on a map then our default map is 67thway_v3 which may crash several times again before it stops crashing for the rest of the night. We see to get a lot of crashs in a short space of time then it stops.

Also having this random crashing with my server in TTT game mode,

I was able to grab this from one of the crashes

23:28:56 Engine error: Player\arctic.mdl (2) at -1.$ -1.$ -1.$ in contact with Player\arctic.mdl (2) at -1.$ -1.$ -1.$, crash. dist = -1, minq = 99999999999999998000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000

Mucked install, no doubt.
Reinstall your server.

[NiandraLades]

It's only happened since the latest gmod update.

[Crashdoom]

I have to say that my personal server keeps having this issue as well, the crash dump gives nothing useful at first glance except: "The thread tried to read from or write to a virtual address for which it does not have the appropriate access."

However, after debugging the still active process, it breaks at vphysics.dll!71b3a7e9(). The map it appeared to crash on was ttt_67thway_v3, so I'm unsure if it's a prop issue on the map or if there's a glitch in the physics system in its entirety.

Maybe this'll help someone figure out the problem, a lot of people have just said it's a Source physics issue and can't be fixed.

Exact same issue we're having, breaks on vphysics.dll, tries to access the memory location 0x000000 if I remember correctly.

[Sidewaykill]

Nope, this has only started happening after the update to a large amount of servers.

[Jonzky]

Also confirm its happening to me on multiple maps,
Engine error:

L 05/07/2013 - 04:08:36: Engine error: player\guerilla.mdl (2) at 26.5 17.6 -30.0 in contact with player\guerilla.mdl (2) at -1.$ -1.$ -1.$, crash. dist = -1, minq = 99999999999999998000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000000

[Sidewaykill]

Perhaps it slipped through Garry's testing? It is a rather rare occurrence.

[NiandraLades]

We reinstalled our server files. Everything was going well until a few minutes ago when we just crashed again.

Brilliant.

[Jonzky]

Server crashed again here, I have a feeling it was caused by a body (ragdoll) being thrown outside (or to the boundry) of the map.

Try it and report back if you are willing to.

[Sidewaykill]

I noticed a time when it happened:
I crowbared an Innocent to death (I was a Traitor) on ttt_67thway_v4, in the barn, on the top part of the barn. His body fell down, then just spazzed out everywhere and then the server crashed. So I'm thinking it's an engine error of some sort.

[Bo98]

Funny how no one has even bothered to report this as a bug.

[Samg381]

Well we need more people who report this as an error for it to get noticed.What model is it? Is it a counter strike model?

[NiandraLades]

I've had it happen on both the Guerilla and Phoenix model, I don't think it's restricted to just player models as it doesn't always say the second error about model, I have always seen crazy physics on prop however.

[Pandaman09]

Leet model also does it. (TTT)

[Samg381]

So it has to be only counter strike terrorist models. Hmm..

I can confirm this as well, near the barn area, facing over the wall, Someone died near that area and their body began flailing about by itself, looked like it has been possessed or something of that nature. After a few seconds of this behavior, the server crashed.

The error was related to crazy physics, the same thing being reported above.

[hatton700]

This is probably going to sound stupid and patronising but do you have the CSS and HL2 content on your servers? This fixed the problem for me...

[deraphel]

This is exactly what's happening to my server. Was there ever a solution to this problem?
I would really need one!

//AMBRO MADE THIS - TOSS IT IN LUA/AUTORUN/SERVER

hook.Add("Think","AMB_CrashCatcher",function()
	for k, ent in pairs(ents.FindByClass("prop_ragdoll")) do
		if IsValid(ent) then
			if ent.player_ragdoll then
				local velo = ent:GetVelocity( ):Length()
				if velo >= 1500 and velo <= 2499 then
					AMB_KillVelocity(ent)
					ServerLog("[!CRASHCATCHER!] Caught velocity > 1500 on a ragdoll entity, negating velocity and temporarily disabling motion.\n")
				elseif velo >= 2500 then
					ent:Remove()
					ServerLog("[!CRASHCATCHER!] Caught velocity > 2500 on a ragdoll entity, removing offending ragdoll entity from world.\n")
				end
			end
		end
	end
end)

function AMB_SetSubPhysMotionEnabled(ent, enable)
   if not IsValid(ent) then return end

   for i=0, ent:GetPhysicsObjectCount()-1 do
      local subphys = ent:GetPhysicsObjectNum(i)
      if IsValid(subphys) then
         subphys:EnableMotion(enable)
         if enable then
            subphys:Wake()
         end
      end
   end
end

function AMB_KillVelocity(ent)
   ent:SetVelocity(vector_origin)

   -- The only truly effective way to prevent all kinds of velocity and
   -- inertia is motion disabling the entire ragdoll for a tick
   -- for non-ragdolls this will do the same for their single physobj
   AMB_SetSubPhysMotionEnabled(ent, false)

   timer.Simple(0, function() AMB_SetSubPhysMotionEnabled(ent, true) end)
end

It's a hacky fix but it works

[Swiftone]

I don't know about you guys but I have been getting this error for about a month now. Server STILL crashes randomly everyday.

Crazy physics on [427][prop_physics] [Ang:-1.#IND00,1.#QNAN0,180.000000] [Pos:-1.#IND00,-1.#IND00,1.#QNAN0] - removing

[spykr]

Don't want to bump such an old thread but this crash is STILL happening 7+ months later and the thread about it which Garry replied to once and never addressed again ([url]http://facepunch.com/showthread.php?t=1269050[/url]) has since been deleted.
It's pretty ridiculous I've needed to keep a script on my server for the last 7 months that freezes ragdolls constantly to prevent this crash.

[roachdaripper]

Sorry for extremely large bump but.. Having the same issue. It's pretty bullshit that we have to do this in order to stop the server crashing on a daily basis.

The solution is in the thread, install it and I assure you it will never crash again provided your server is stable.
