Sim Owners - How often does your sim crash?

I've had my sim for about 2 weeks now (new Class 5). I know it's a little overburdened with scripts, but our total frame time stays between 22 and 23. I've heard that 25 is where it gets pretty bad. We've had 12 crashes in 12 days, not counting restarts. What are some of you seeing on your own sims? I'm especially interested in hearing from some script heavy sim operators.

Also, does anyone know a projected delivery time for the Mono upgrade?

Edited to add: We're running fine in between the crashes. Since the last restart of last week's update, it's been running great, right up until the crash.

My sim has never crashed, it's gone on a go slow and I've reset it but I doubt I've reset it 12 times and I've had it months.

Most of my resets have been due to griefing with a mega prim put over the land but now I know what to look for.

Rarely, heres the trick......

If you have a class 4 sim, you'll want to keeep the scripts down below 15ms
If you have a class 5 sim, you'll want to keep thw scripts down below 5ms

The servers are able to evacuate about .500 MS on each object per cycle, if you have a object running at higher than .500ms then your going to have issues,, it will culminate into a higher script lag each cycle that it stays above .500 ms. Once you hit about 30ms, its critical go much past that and your looking at a downed sim, depending on how bad the script usage was when it crrashed you might be down for hours, when the sim comes back up , be sure to find the object that made it happen.

More often than not the normally mundane N30 modeling studio will be the culprit, I dont know what it is about that product, but N30 Studio seems to run higher than .500 ms when not being used, I can only imagine what it uses while in use. Also some saltwater fish from a dealer called KK seem to make lots of collisions, that can add to a sim crashing.

Be sure to watch your script usage!

I'm guessing that's a typo, you suggested that Class 4 can handle 3 times the amount of a Class 5. Typically whenever I've been watching, no scripts are running that high by themselves. Occasionally I do see one go close to 1, but only momentarily. Our top 400-450 scripts usually come in around 7-9ms. I've never seen the total frame time hit 26 unless it was momentarily as a script heavy avatar teleported in. Also, our physics numbers are near zero.

I have no idea what the N30 modeling studio is, but if you can tell me I'll see if any of the residents has one.

How can you tell what object caused a crash?

The thing that kills sims mainly is physics.

If you have people bouncing stuff around, riding rockets or playing games that have physical attributes, that's your best bet. Secnodly a high avatar count.

For example, I built a bowling alley and if you get a strike, 11 physical pbjects interacting. one in 30 times the sim dies. Riding rockets is fun but about one in 5 times it'll kill the sim.

My sims are generally VERY stable but if you have 40 people o one.. then yes I think they will crash about once a day with that load, that's just the way it is.

seems like many of the sims on the newest continent go down between 1-4 times DAILY!

Lower MS is better, Class 5s should be in the single digits, Class 4's high singles to mid teens, I presume Class 3's where in the 20's or 30's

That doesn't make sense to me. Shouldn't the better hardware be able to handle higher loads? I'm not an IT guy, the way you describe it, it sounds like we should all want class 3 sims.

In the past year and a half, Ive seen it go down twice.

My sim has crashed 176 times in 24 days thats an average of 7.3 times a day, its very anoying. How do you find out what class sim you have?

I'm on a class 5 which I reset almost every morning, but the photographer with the N30 just moved out, so we'll see if that makes any difference.

But it hasn't actually crashed in the 5 weeks I've had it.

wow..are you using megas?..have you tried showing updates to see what scripts are constantly updating..how many toruses are in builds..how much alpha is used in textures..how many constant running scripts like "listening scripts" do you have that are constantly running?

Thats way too excessive..wheres your sim?..let me visit!

I've had a lot of experience with crashing sims, and 99% of the time, it's physics, there's only been a few cases in SL history where script exploits could bring down a sim. You need to check into collisions, avatar inter-penetrating prims on sit or TP, etc. Be very wary of physical toruses. Physics is the key.

I'm not the owner, but Livingtree usually runs at around 44-45 fps. We had had some crashes (I crashed it during a particularly intense fireworks show on Friday evening), but it's highly uncommon.

I think he's saying that the newer class hardware consumes less time executing the same scripts..

N30s should be kept in sleep mode when not in use, IMO.

My (class 5) sim Waikiti has had about 20 reboot events in the last two months. That includes estate-manager restarts and maintenance restarts (rolling restarts etc), so the actual number of crashes is lower. Interestingly, my (class 5) openspace sims (which are new) have not had any crashes at all in the 4 weeks since they arrived.

In my experience the majority of the crashes seem to be physics related. There's quite a few vehicles on the sim, we do love our planes and boats

If there's one in your sim you'll see it at the top of your top scripts list, trust me. Luckily, the thing does have an auto-shutoff mode in the maintenance settings. I think you actually have to click 2 buttons to force it to shut down after the timeout period. I'd advise anyone who owns rental sims to make sure residents set their N30's to auto-off.

EDIT: Also, a sim owner can only use trial and error to determine the source of a sim crash. If you ask the Lindens to monitor your sim's performance they can often give you coordinates of problem areas in your sims after a few days of watching the logs.

There is no easy way for a resident to tell anymore (not even the tracert method is reliable anymore). Just contact Concierge via live chat and they can tell you.

On Doc is the sim, I sell neons with a few flashing scripts and 1 greeter and 1 spy/chat log script. Could they cause problems.

I dont think im the one crashing the sim because it has only been happening on this sim, i mover just before Feb from a different sim after I had a very reasonable offer for my land. I have virtually the same setup here and had no problems on the old sim that i know off.

Also the Lag and crashes seem to be random, but alot of buildings have gone up since I moved here so alot is going on hereat the moment.

Im really a bit of a noob to all this, Only been on SL since Jan 08. So if im crashing the sim with a script I would rather know and fix it

No... you see, the faster the server, the less time it has to spend on a given task. The stats are more a measure of how much resources the server has to expend to service scripts. Given the same number of scripts that use the same amount of resources, a class 5 server will have to spend less time handling them than a class 3. This is a completely different metric from the Script Performance deal listed in the stats bar, by the way.

I really wish this forum had multi-quote capabilities so I could easily respond to all these things in one post. I wanted to note that there are at least a couple different causes for physics crashes:
- Physical objects interacting with each other (that is, objects with the Physical property enabled and quickly banging next to each other or interpenetrating).
- Avatars interacting with or interpenetrating non-physical objects (especially megaprims and sculpties). Avatars are physical entities, and they will cause physics collisions when they get tangled up with prims, physical or not (as the collision detector in Region Tools usually points out).

Didn't know they had one!

Yups! I dun remember what channel they're on (7?), but type "/(number) sleep" should do the trick.

I manage 32 sims. I get a request to restart a sim about once a month, it's a very rare thing. Unless someone has a problematic object, our stats show between 44 and 45 sim FPS. A sim crash is also very rare. Maybe because they're private estate sims?

I can't imagine putting up with some of the things some posters are dealing with, I'd go crazy with so many issues! I strongly recommend you document and call concierge service.
