Modded Server Crash

[KR1dude]

Hi! I'm trying to make a server for my modpack and I want to make it run as efficiently and smoothly as possible. So, I wanted to use these parameters for it:

java -native -server -Xincgc -Xmx6144M -Xms2048M -Xmn512M -XX:NewRatio=3 -Xrs -XX:+UseThreadPriorities -XX:CMSFullGCsBeforeCompaction=1 -XX:SoftRefLRUPolicyMSPerMB=2048 -XX:+CMSParallelRemarkEnabled -XX:+UseParNewGC -XX:+UseAdaptiveSizePolicy -XX:+DisableExplicitGC -Xnoclassgc -oss4M -ss4M -XX:+UseFastAccessorMethods -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=75 -XX:+UseConcMarkSweepGC -XX:UseSSE=4 -XX:+UseCMSCompactAtFullCollection -XX:ParallelGCThreads=4 -Xcheck:jni -Xfuture -XX:+AggressiveOpts -cp "minecraftforge-universal-1.6.4-9.11.1.965-v164-pregradle.jar" -jar "minecraftforge-universal-1.6.4-9.11.1.965-v164-pregradle.jar" nogui

pause

I ran the server with these and it worked fine, but it crashes at the end right before it generates the map. It states this:

---- Minecraft Crash Report ----

// I bet Cylons wouldn't have this problem.

Anybody know why and how I can fix this? Thanks for reading.

You cut off the part of the crash report that would have let us help you. That error message means that you have not removed one or more client-only mods. It is impossible to tell which without the full crash report or a link to your pack.

Found the problem. Accidentally left OptiFine in the mods folder. Thanks for the help.
