Problem Tech World 2 Server Constantly Crashing

[Everettq]

I have a Tech World 2 server that will NOT STOP CRASHING. After I start it up, it works fine for about 5 minutes and then it starts getting very slow and eventually stops responding or closes itself.

First, I got some errors regarding the portal gun mod, so I removed it. Then, every time I did something with a Thermal Expansion pipe, it crashed. So I downgraded the Thermal Expansion version and that problem was fixed somewhat. Then every time I started up a Build Craft quarry, it crashed. So I removed Build Craft too. But it sill crashes randomly with "Exception: java.lang.OutOfMemoryError thrown from the UncaughtExceptionHandler in thread "Thread-5"" and the server process won't close until I force quit it about 5 times. Other times, it just closes and it says that it deleted the crash report! Why, thank you server, that's very useful.

My friend and I are getting really frustrated and it is becoming unplayable. Please help.[DOUBLEPOST=1406847260][/DOUBLEPOST]I also had to downgrade the Applied Energistics version because using an ME terminal made it crash too...

Oh and this is my start.command file:
#!/bin/bash
cd "$(dirname "$0")"
exec java -Xmx20G -Xms10G -jar Server.jar nogui

Yes, I'm on a Mac...

Uhm, we need logs and crash reports before we can diagnose anything.

This appears to be the latest one.

But it does say that "Some errors may have been discarded"...[DOUBLEPOST=1406849971][/DOUBLEPOST]It has crashed many times since then and it hasn't made any more, so whats in there might not be the whole problem.

Do you have / have the most recent version of Dragon API?

Also, you should increase the allocated memory to solve the Out Of Memory error

 

[Everettq]

It is version 16d, which doesn't appear to be the latest as that is version 25g.[DOUBLEPOST=1406850202][/DOUBLEPOST]I tried the 25g and it crashed immediately, along with the client. The server crash report is attached.[DOUBLEPOST=1406850233][/DOUBLEPOST]Does it really need more than 20 gigs?

 

[Everettq]

Also, I looked in Activity Monitor (the Mac version of Resource Manager, I think) and it says the server was only using about 8 gigs when it gave the memory error.

Ok, never mind. I quit. The damn thing corrupted my world and all my backups. I hate FTB and all the shitty coding that goes into it. I'm leaving.
