Server Can't Keep Up Issue, But More!

ok so i have bukkit i got it off an auto installer. in order to change the amount of ram i need to right click the icon and click edit. so i do that and this shows up

Echo OFF
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="64" java -Xms4096M -Xmx4096M -jar "%~dp0craftbukkit.jar"
IF /I "%PROCESSOR_ARCHITECTURE:~-2%"=="86" java -Xincgc -Xmx4096M -jar "%~dp0craftbukkit.jar"


so the 4096's i put in. how do i configure that exact file to get 4 gigs of ram, because this keeps happening in my server:

a ton of cant keep up messages, but i typed /ram and it says im using like 3000 some mb, so how come it keeps sayin it cant keep up. i just gotta new map

 

use this one BUT adjust the ram values
Echo OFF
SET BINDIR=%~dp0
CD /D "%BINDIR%"
java -server -Xmn4G -Xms8G -Xmx16G -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XXarallelGCThreads=5 -XX:+CMSParallelRemarkEnabled -XX:+DisableExplicitGC -XX:MaxGCPauseMillis=500 -XX:SurvivorRatio=16 -XX:TargetSurvivorRatio=90 -jar craftbukkit.jar
PAUSE

 

better use bukkit gui it can solve your problem http://dev.bukkit.org/server-mods/bukkitgui/

i tried that and unfortunatley this came up in the log

Unrecognized option: -XXarallel1GCThreads=5
Error: Could not create the Java Virrtual Machine
Error: A fatal exception has occured. Program will exit
Press any key to continue . . .

what should i do?? please help ash

are you running java 32 bits?

 

Code:

-XXarallel1GCThreads=5 should be -XX:ParallelGCThreads=5

that was just the error code, not the actual code causing the error. the code u gave me, do i put it in the RAM file thing, or r u saying i typed wrong cuz i didnt.

ashley
no 64-bit i have a 64-bit laptop

 

The error looks as if it was typed/pasted wrong into the batch file. I figured because the forum made the : and P into a smiley face in ashley's post, you may have just copied and pasted into your batch file. This would have left the : and P out leading to the error.

OH! OKAY THANKS!!!!! it works liek the server, but im wondering when ashley said to change the RAM values what should i change them to with a 64-bit 8gig laptop. i want like 4-5 gigs on the server, and i changed all the values to 4, but that didnt work, like it wouldnt start, then i change it to 2,4,6, and taht worked, but how do i know if i have 4 gigs on it. how can i get 4 gigs for sure?

 

This is a bit off-topic, but in case you didn't know you can turn off those annoying "Can't keep up" messages in the configuration. They drove me crazy lol

 

-Xms4G will set the inital heap memory to 4GB.
-Xmx5G will set the max heap memory to 5GB.

Keep in mind Java will use a some memory beyond heap memory, but heap memory is where most of everything goes. So with -Xms4GB, you will for sure have 4GB of memory allocated to the server.

u have been a tremendous help, if u wanna get on the server its 75.185.19.160 OR 184.57.32.35 save BOTH!
