Descriptive Problem Summary:
Since the implementation of a new lighting system, clients have been crashing regularly, usually when jumping from area to area (rather than scrolling across the screen). Some people crash more regularly, some less.
Here are a few windows crash logs of the issue:

I'll check out those details soon, and hopefully can get that patched into 508.1287 if I can find the cause.

I just experienced a crash on the same server that Zomgponies and Krausus are on, here's the info from mine:
Problem signature: Problem Event Name: APPCRASH Application Name: dreamseeker.exe Application Version: 5.0.507.1286 Application Timestamp: 55694a6e Fault Module Name: byondcore.dll Fault Module Version: 5.0.507.1286 Fault Module Timestamp: 55694996 Exception Code: c0000005 Exception Offset: 0005b1e5 OS Version: 6.1.7601.2.1.0.256.48 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 | |
The second crash is in icon manipulation routines; specifically, it's in the routine that clears the icon, so this is probably happening as an icon is being destroyed. Still looking into the first case. I suspect they're related.
[edit] The first crash appears to be in the animation message handler. I suspected animation was involved from the beginning so that makes sense. Looking into that further. | |
Animation crashes are probably the most important ones as those would relate directly to our new lighting system. Either way, both should return runtimes at worst, client crashes aren't really debuggable from our end.
| |
It's impossible for a client-side issue to return a runtime error.

I experienced a crash similar to what ZomgPonies and Krausus have described, it is also on the same server as both. The Windows crash log is below.

Crashes used to be quite frequent but less so now but still an annoyance

There are sanity checks in 508 against the animation issue, so I would suggest trying this in 508.1289. If new crash reports appear, please post them here.
| |
Crashes appeared to happen less often with byond 508.1289, but they appear to be happening more often again on 508.1290.
Same server as all the others (Paradise). This report happened as soon as I focused another window on top of dream seeker, so anything that may have prompted it was missed: Faulting application name: dreamseeker.exe, version: 5.0.508.1290, time stamp: 0x5588c0b5 Faulting module name: byondcore.dll, version: 5.0.508.1290, time stamp: 0x55888cc5 Exception code: 0xc0000005 Fault offset: 0x00057159 Faulting process id: 0x2834 Faulting application start time: 0x01d0ad678d4eb0f5 Faulting application path: C:\Program Files (x86)\BYOND\bin\dreamseeker.exe Faulting module path: C:\Program Files (x86)\BYOND\bin\byondcore.dll Report Id: f09c911c-195a-11e5-8ffc-001d60bef81e | |
1289 seemed to fix the crashing issue that was plaguing us - only managed to get one crash on it:
Faulting application name: dreamseeker.exe, version: 5.0.508.1289, time stamp: 0x557a2ea6 Faulting module name: dreamseeker.exe, version: 5.0.508.1289, time stamp: 0x557a2ea6 Exception code: 0xc0000005 Fault offset: 0x0002b629 Faulting process id: 0x2068 Faulting application start time: 0x01d0aa3a4724baf0 Faulting application path: C:\Games\byond\bin\dreamseeker.exe Faulting module path: C:\Games\byond\bin\dreamseeker.exe It seems 1290, however, is a bit less stable...

I suspect 508.1289 and 1290 probably aren't significantly different here. I'll run some traces on this info and see what I can find.
| |
The ntdll.dll crash in 1290 is untraceable; the crash in byondcore.dll happens in the icon destructor, which likely means the problem is somewhere else.
The 1289 crash on the other hand, in dreamseeker.exe, yielded better data. I found that a sanity check in the hit test routine was being done in the wrong place. This does not explain the icon destructor issue but I kind of think these are all related. I'm still trying to track this down. If you can come up with any kind of test project that reproduces this reliably (mayhe try to use that lighting system in an otherwise basic project, and stress it?) that would be a huge help. | |
Possibly related due to the usage of the same lighting system, (the crashes only occur when using this specific system, it's highly efficient but it apparently causes crashes), we had one round in which almost all players had nearly continuous client crashes caused by movement of the user it seemed.
It doesn't happen on a per round basis, but appears that when some trigger is activated (that I have no way of identifying yet), the rest of the round will cause these continuous crashes for all players. (I'm not sure how to generate one of the crash reports shown above) Problem signature: Problem Event Name: APPCRASH Application Name: dreamseeker.exe Application Version: 5.0.508.1294 Application Timestamp: 55aadcc9 Fault Module Name: byondcore.dll Fault Module Version: 5.0.508.1294 Fault Module Timestamp: 55aadbde Exception Code: c0000005 Exception Offset: 0005ba75 OS Version: 6.1.7601.2.1.0.768.3 Locale ID: 1033 Additional Information 1: 0a9e Additional Information 2: 0a9e372d3b4ad19135b953a78882e789 Additional Information 3: 0a9e Additional Information 4: 0a9e372d3b4ad19135b953a78882e789 | |
I have crashed before on paradise, and under both wine and windows, but not very frequently. Maybe twice before in as long as I can remember. I don't have crashlogs, but I can offer that I live in west coast america, and paradise is hosted in sweden. I've often noticed that moving around as a ghost or teleporting (which can happen at sanic speeds due to low ticklag) can lead to the client having to noticeably catch up with all the lighting overlays and objects while it displays the fullbright undertiles/atoms. These are usually the point that my client would crash.
Is it possible that, while the client is catching up to lighting arrays, it gets instructions to animate an icon or overlay or such that hasn't been loaded yet? | |
Lummox JR resolved issue with message:
A longtime crash that was manifesting in icon destructors was found. This was caused by the client garbage collector firing while the client was trying to resolve a client-side icon operation, when the garbage collector deleted one of the component icons prematurely. | |
Adding a note that NethIafins was instrumental in sussing out the cause of this bug.
| |
I'm not sure what the exact reason for using /atom/movable was, but I would guess it was simply easier than making a new /obj and making sure everything else ignored it.
The crashing occurs unpredictably, with some people crashing far more frequently than others, and most crashes occurring when trying to load an entire new screen of turfs. It seems like the frequency of crashing may be related to latency to the server.
