NEM Supernode Rewards Program


@nemstar: that looks ok, so you need to wait until website shows the current test results.


ok, I thought the results were up to date, because they show date and time of today.


that is the time when the completed round was analyzed.


IP change requested. Please add. Thanks.

EDIT : To people who want to upgrade, please consult - NEM Supernode Command Line Tutorial for Debian 8.4
It has got all the details.




This round is still being payed out. Wait for a few hours. You’ll get it.


Hi There,
again one of our nodes (nemster) failed chain part. Nemster_2 passes. Both nodes have been installed identically. Any ideas?


Bad luck, nothing else.



i created two new nodes:

Both are on different 16 GB SSD VPS. only starts with 1G-1G settings. starts easily with 4G-8G settings.

Nodes are not synced. @cryptoBeliever checked them and asked to post here.


On purpose or do you want that node to use more RAM?

This one is synced, the other one is syncing right now.


On purpose 1G-1G. it will crash with more ram. Nodes are exactly the same.


Why crash? the vps has 16GB i thought?


When i try to run *.bat with bigger memory settings it only blink and stop.


And task manager really says the vps has 16gb? Also what is the log output when it “blinks and stops”? Is it really java 64 bit that is installed on that machine?


Java version 8 Update 181 (build 1.8.0_181-b13) confirmed.

idle 1.4/16 GB and loading blocks 2.1/16GB

CPU is 50-70% of 2.20GHz while loading

Connection speed was a couple days ago almost 1000/1000 Mbps but now it is
PING 54 Download 60 Mbps and Upload 350 Mbps BUT i had same problem also
couple days ago.


Can you paste the startup script? Should not exit when more than 1G is configured.


I changed OS to Win 7 and now i can use different settings for memory.

Both nodes start with this setting:

pushd nis
java -Xms4G -Xmx8G -cp “.;./;…/libs/” org.nem.deploy.CommonStarter


My node has failed in “Responsiveness” Since around September.
I do not know the cause.
I want you to help me.



Start Script

java -Xms2800M -Xmx2800M -XX:+UseG1GC -XX:MaxGCPauseMillis=200 -XX:+PrintGC -Xloggc:"./gc.txt" -cp ".:./*:../libs/*" org.nem.deploy.CommonStarter
java -Xms512M -Xmx512M -cp ".:jars/*" org.nem.rewards.servant.NodeRewardsServant

Did you try restarting NIS?


I restarted NIS and VPS.
If restarted, it may be successful.
