Windows .exe Exception-Access-Violation

[JorrdKarrd]

Hello!

Since upgrading to Unleashing and DW 1.5.2 from Ultimate and DW 1.4.7 I've been suffering from constant crashing, I've digged around for hours with no results.
I followed the Basic Troubleshooting guide thoroughly with no luck, I updated my graphics driver and I tried bumping up Permgen memory and memory in the launcher options, I even tried playing without a texture pack to see if that was the culprit but it always crashes to desktop immediately after 10 minutes aprox of gameplay.

I would sincerely like some assistance, any ideas or links are welcome. I don't know if I pastebin'd the correct log so please tell me if I need another one, I haven't had to contact support before.

Thanks!

Welcome. I normally would say go through the trouble shooting guide, but you said you have already went through that guide, not another one, right? Could you post a console log in debug mode to pastebin.com Look here for more info about the logs.

Since it has a set pattern of ~10 minutes I wonder if it might be an AV program. Check the console log for something like this '(The requested operation cannot be performed on a file with a user-mapped section open)' If it appears your AV program is keeping minecraft from using the file that it needs. If your AV has a place for exceptions then add the launcher folder, the one in which your mod packs are in, to that list. If it does not appear in the console log, please still provide the console log as it might still provide the answer. The AV program is just my assumption without having the console log.

Yes, I read a ton of other posts to try to identify my problem with others, but I didn't find a solution.

So yes, I went through THAT particular guide indeed
I'll disable my AV right away and see if it helps, right now I'm testing it with a completely fresh Unleashed install, I just can't figure out what it could be, I read somewhere that 0x00005 is a memory related issue, but increasing the allocated memories hasn't helped at all.

My last session lasted for 30 minutes or more. It ALWAYS crashes when I perform an action, breaking a block or hitting a mob for example - I don't know if that is relevant.

I'll report back with my results of disabling my AV.

 

[JorrdKarrd]

After 5937 seconds (100 minutes) it crashed with the same error with AV completely turned off.

Crashed after 6 minutes while digging up a lot of sand, it seems that the crash intervals are drastically shortened by breaking blocks continually

 

[JorrdKarrd]

I enabled Debugmode in the launcher console, however I'm unsure how to find it's log. If it's the same location as before then I have a pastebin of my crash report with Debugmode enabled.

From your log:

# Problematic frame:
# C  [OpenAL64.dll+0x6220]]
j  org.lwjgl.openal.AL10.alSourcei(III)V+0
j  paulscode.sound.libraries.ChannelLWJGLOpenAL.attachBuffer(Ljava/nio/IntBuffer;)Z+39
 
Desktop\FTB\Unleashed\minecraft\bin\natives\lwjgl64.dll

This indicates a problem with your audio ( OpenAudioLibrary64.dll ). I remember I also had a similar problem.
First, play for as long as you can with all sounds completly muted. Both in Minecraft, Windows and speakers.
Try updating sound drivers, check your audio card is fine and also, update LWJGL:

Just put the LWJGL files in the .ftb\Unleashed\minecraft\bin folder.
Hope this helped.

It seems that my issue was resolved by replacing the lwjgl file (with the horrible side effect of random FPS drops, although it seems to only occur in the twilight forest.) I no longer crash Thanks for your help

 

[JorrdKarrd]

Hello again,

after a few days of testing and trying to solve my FPS problem that supposedly came with the previous lwjgl fix, I can safely determine that my FPS does not improve at all by lowering video settings and trying to bump up the performance, I at first thought it only affected me while in the twilight forest but this was not the case.

With the fix I can play with perfect performance for about 5-10 minutes and then it turns into a FPS drop nightmare to the point of it being unplayable. I messed around with my world a bit and the FPS goes bonkers even with all mystcraft/twilight forest worlds unloaded and with all machinery turned off.

I would also like to point out that my performance is perfect at all times without the fix, except for the constantly random crashing. I also updated my Realtek sound drivers with no results. Could there be another possible fix to this? (I followed the instructions that Guildmaster linked precisely and with the correct 64 bit system file provided.)

Right now I'm trying to test my world and attempt to get a copy of the console log, I noticed that there are an absolute ton of errors in it, particularly a "net.minecraft.world.chunk.storage.AnvilChunkLoader.func_75823_a(AnvilChunkLoader.java:412)"

Heres my log: http://pastebin.com/HW3p347S

Could you post your system specs? Especially, your processor, your RAM, graphics card(s), hard drive or SSD and also, are you on a laptop or desktop PC? It could happen not because of a mod or another, but rather you not having a good system or a good configuration.

Also, by reading your log, it seems you have changed the config files of some mods. If you did not you should make sure no one did, or that you don't have malware or something changing it. Basically, Minecraft is complaining it's having a mismatch between the mods in your world and those in its .ftb/ folder.

 

[JorrdKarrd]

Radeon 6950 HD 2GB / i5 2500k 3.3ghz / 8 GB DDR3 RAM / 120GB SSD (running FTB on this one) and I'm on a desktop PC.

I did mess with two config files, enabling world anchors from Railcraft and disabling shaders from MachineMuse which prevents NEI F7 mode. I will do another clean install and see if that helps.


With a clean install I still get a massive amount of errors, luckily I always backup my saves on a regular basis, however the only save that wasnt "corrupted" was at the point of when I had only built a house, which makes me curious as to what was causing the massive amount of errors, I don't understand how the ID's could be mismatched. The only machinery I had set up was 2 coke ovens, pulverizers with induction furnaces and a quarry in the Twilight Forest, but having a quarry in TF wouldn't be the cause of this, would it?

At this point I can just rebuild and hope the errors don't come back since it's probably my world save that was the cause of the errors.

I'm afraid finding the source of your world's corruption would require far, far back, in a time long forgotten, right after you generated the world. You would have to check your world's history to find the culprit. Generally, don't ever change configs after the world was made. Not even one thing. Maybe some stuff is safe, maybe it's not.
Here's a tip: don't backup just your world. Do backup the configs, too. Also the mods folder. When you believe your world got corrupted, check the files of your mods and configs. You could use md5 or sha algorithms, if you really really are that a computer geek and want a thorough check.
Actually, you can make a simple .bat file to backup your .ftb folder.

I am getting the no sound problem too. When I turn on Sound FTB Minecraft crashes. Vanilla MC sound works fine.
When I download and copy/replace the dll files, and start FTB new files are downloaded and my replaced files are overwritten.

I have not really been following the converstation so I'm not sure if this was suggested. After reading your last reply you could try updating the lwjgl in the mod pack folder. In FTB 1.5.2 the lwjgl is version 2.4.2 Vanilla 1.6 uses lwjgl version 2.9.0 Use this guide to update the lwjgl in the mod pack folder if you choose to. Substitute the mod pack folder for the references to the %AppData% folder. As always make sure you have a back up of your saves and configs before trying anything.
