Server running out of memory and lagging.

my plugins: http://gyazo.com/9c67eb0b7723aec83028e7691dc98ecf

my server keeps running out of memory every 30 min - 5 hours then lags very bad, every time the memory goes down the tps goes to 5 and under.

The server its running on:

• Intel® Core™ i7-2600 Quad-Core
• 32 GB DDR 3 RAM
• 2 x 3 TB SATA 6 Gb/s HDD; 7200 rpm (Software-RAID 1)

We have it running off 7 gigs of ram on that. We have tried changing to other plugins (the less essential ones) but it didn't fix. The Server gets to about 80-120 people on at a time during the day and about 30-80 at night. Please help :3 Thanks

 

Could you provide a logfile extract where one of those crashs happened?

 

it doesn't crash, it just lags very bad and /mem shows no memory left, then it sorta fluctuates between a couple of mb of mem left and half a gig, and lags, which only a restart fixed.

 

Malo what startup code are u using?

 

jacklin213
java -Xmx8024M -Xms128M -jar craftbukkit.jar nogui

I guess 8 gigs lol, but when i do /mem

WAHHH u start your server at 128MB ???? o.0

 

what should i have it as then?

 

whats so crazy about that? lol

 

Well I have mine at 1gb and it only ever says the warning messages when I'm uploading videos to utube , saving video's with wlm , whole computer virus scan and recording with fraps all at the same time

 

but that has nothing to do with it running out of memory.

 

Well that is why it displays warning has the time changed or is the server over loaded

Sryz my bad it maybe ur CPU usage due to 1 plugin

 

My guess is a disk I/O bottleneck.

After all you are only running two standard disk drives in RAID 1.... They're not that great with sequential speed, let alone random reads/writes, compared to an SSD. Try your world and maybe some plugins in a RAMdisk and see what happens.

 

Try changing to this and let us know:

Code:

java -Xincgc -Xmx8G -jar craftbukkit.jar

 

ah the -Xincgc i c it again and only know half of the meaning (too lazy to read the wiki) all i know is its called the something garbage collector and it works very well

 

If there still is a problem, try remove permissionex and replace it with any other ones out there
