Server Crashes after a few minutes

[Prfndhatrdofman]

So im finally reaching out to the community on this. Have had lots of trouble with Direwolf20 1.4.6 pack. Started with some serious lag issues for all users, but i resolved that with another thread that had some commands for the batch startup file.

• Windows 7
• Local Server: AMD X2 2.4 ghz 4800+ 4 GB Ram Java 7.10
• Direwolf20 1.4.6 Pack
• Start the server, runs normally for about 5 minutes then randomly closes. No error on screen, but an error log is saved to the server folder:
• A fatal error has been detected by the Java Runtime Environment:
  #
  # EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x0000000071efa35b, pid=3036, tid=1056
  #
  # JRE version: 7.0_10-b18
  # Java VM: Java HotSpot(TM) 64-Bit Server VM (23.6-b04 mixed mode windows-amd64 )
  # Problematic frame:
  # V [jvm.dll+0x3ba35b]
  #
  # Failed to write core dump. Minidumps are not enabled by default on client versions of Windows
  
  
  
  If I can provide any more information I will. If anyone can help id appreciate it. IM beating my skull in with this one.

I'm having the same problem.

This seems to be a crash in the JVM, not Minecraft. May be an incompatibility with the Java version but I'm starting to doubt it as more users would probably have reported it.

My setup:
Windows 7 x64 build 761 SP1
Intel i5 750 Quad Core - Standard clock
8GB memory

All instances of the servers run with Administrative privileges.

Pastebin of the full error: http://pastebin.com/jC4mQKi2 - note, the pastebin link will expire in 30 days.

Versions of Java tried as of yet:
- Java 7 update 9 x64 (1.7.0_09-b05)
- Java 7 update 11 x64 (1.7.0_11-b21)

Server packs having this issue:
- FTB Server Direwolf20
- FTB Server MindCrack
- FTB Server Magic World

Server packs not having this issue:
- An old Tekkit 3.1.3 Server

Can you upload the full log to pastebin orso?

You have java 6 and java 7 installed?

Hey,

Here's an update on this. This problem is now solved for me.
To answer first, I only had Java 7 installed. Sometime in the past I probably had Java 6 installed on the machine. I do have Java 3D though and it looks like there are some references to that in the jre6 folder (it also has it's own Java3D folder.

Note, I always made sure from the start to check out what the results were from running "java -version" in a command line and it always gave out the correct version that I expected it to display.

Solution for me at the moment:
I removed all versions of Java (except the above mentioned Java 3D) by uninstalling from the Control Panel > Programs and Features.
I went to the Oracle Java 7 archive page here (note I had to create an oracle account, but that was pretty painless): http://www.oracle.com/technetwork/java/javase/downloads/java-archive-downloads-javase7-521261.html
I decided to try out version 7 update 5 so I downloaded the x86 and x64, installed them in that order to be sure any defaults would end with the x64 version.
The servers have been running without issue continually today and yesterday.

Thoughts and possible things to try:
Is it possible that there is a bug in the newest versions with the server? Not very likely as I'd expect more complaints of this type then.
Is it possible that the path reference that Nessiroj found in my log to jre6 is being a problem with the newer versions? Yes.
Is it possible that the old version of Java 3D that, if I remember correctly, is not being developed any more, atleast in the same way is being a problem? Yes.
What to try then is remove the path variable and jre6 folder and uninstall Java 3D as I don't think I'll be needing it anymore. Then update Java to a newer version and see if the servers stay stable or not.

Hope this helps and I also hope I'll get to do the above mentioned things soon and remember to report in

Good luck
