Mac No extra mods installed. Server tick crash

[d00d123]

FTB Launcher Version: 1.0.5 (most recent update I can get)
Minecraft Version: 1.4.2
Java Version: 1.6.0_37, Apple Inc.
Description of error/how to recreate:I've had this crash about 8 or so times except it seems to have accelerated in the last hour. Before this I could play for 2-3 hours or more even without a crash and now it has crashed 3 times in the last hour. Always a server tick problem. I have no extra mods running(am running vanilla FTB pack).

This is throwing me for a wild one: - Operating System: Mac OS X (x86_64) version 10.8.2
Do you have 32 or 64 bit OS, and does your Java bit type match?

 

[d00d123]

Yep OS is 64-bit. To my knowledge all versions of OSX past 10.5.2 are 64-bit. As for the Java from what I've seen in the logs it is 64-bit as well. Once again I would assume so. If it helps, I haven't screwed with the Java at all. Whatever version is running is I have gotten from software updates/came installed in the computer when I got it.[DOUBLEPOST=1353106423][/DOUBLEPOST]UPDATE: Confirmed Java matches OS bit version (I checked in terminal:

java version "1.6.0_37"
Java(TM) SE Runtime Environment (build 1.6.0_37-b06-434-11M3909)
Java HotSpot(TM) 64-Bit Server VM (build 20.12-b01-434, mixed mode)

 

[Ashzification]

Try uninstalling Java and reinstall Java 6, 64 bit?
I don't think this is the issue, but I'm drawing a blank as for relevant suggestions for you at the moment.

 

[d00d123]

I think the issue here is most likely on my side. I'll probably do that but it is a pain on the Mac given that you can't install versions distributed by Oracle. You have to get the Java distribution that Apple gives out. I figured I'd post just so you all could see it. I've done a fresh FTB install so I'll see if it does a bit better.

I'm no computer noob but I don't have a very good working knowledge of Java so figured it was worth a shot posting. Thanks for trying. I'll reply if I find a fix that other people can use.

Edited: Meant to say Apple not Oracle a second time. Also I'm installing Java 7 right now.

 

[d00d123]

Okay final update for people having the same issue. DO NOT install Java 7 for mac. The launcher doesn't work at all with Java 7. I think we'll just have to wait and see if patches fix this.
