Your new nodes are not showing the delegated public keys that you enrolled with, please check.


thank you!


My supernode is running but failing all the tests after change ip.

The ip in the db was not changed. when did you send the message? Can you give me the tx hash?

I don’t see any such transaction in the main chain.


Strange, in account it confirmed.
Send message again:


Oh, you are right, nembex is the problem. But your message states that old ip is and the db has ip for entry with alias fortune. That is why the ip wasn’t changed i guess.


Oh, i send message to change ip from to early.
but don’t control that it change.
Can you fix it or i need to send new message?


Changed ip manually. Should be ok now.


Thank you. It’s work. Happy New Year! )


Hi, BR, what’s happened with SuperNode measuring among 2019-01-06 12:58 GMT and 2019-01-07 09:14 GMT ?


The result evaluation task was stuck. I fixed it.


Did you find any workarounds after that? My SN also suddenly started failing by responsiveness.
My SN locates in Japan, too.


I resolved it by changing the server to a different company.


Good to hear the solution. Thanks! :grinning:


My SN is failing intermittently on computing power and version. Version is 0.6.96 BETA. Has 4 GB RAM, and two CPUs. Memory usage was around 80% usage by Java, and also have a 1GB swap file.

nis starts Java with parameters: -Xms2800 and -Xmx2800

Any idea why these version and computing power would be failing?


After reboot shows as below while chain is loading:

%Cpu(s): 26.3 us, 0.1 sy, 0.0 ni, 41.0 id, 0.9 wa, 0.0 hi, 0.1 si, 31.6 st
KiB Mem : 4044748 total, 492100 free, 2332472 used, 1220176 buff/cache
KiB Swap: 1048572 total, 1048572 free, 0 used. 1473308 avail Mem


that probably leads to using part of the swap memory which is slow.
Try to use -Xms2500 and -Xmx2500 if we will see if it works better.
Also be sure to restart NIS every few weeks.


I’ve tried changing to 2500 but still failures on computing power.

This is the output from top:

%Cpu(s): 48.4 us, 0.0 sy, 0.0 ni, 0.6 id, 0.0 wa, 0.0 hi, 0.0 si, 51.0 st
KiB Mem : 4044748 total, 160808 free, 3168840 used, 715100 buff/cache
KiB Swap: 1048572 total, 1041056 free, 7516 used. 629260 avail Mem

1264 root 20 0 5174272 2.757g 11292 S 198.0 71.5 1068:00 java

CPU shows as 48.4% in the summary, but above shows 198.0%
Also memory is 71.5% usaed by Java.

Should I lower 2500xms/xmx to a different value?
