Anyone know why this happen? Nothing changed from previous run, after restart computer, it won’t boot anymore. 
I have tried to delete db, change hostname to ip, disable autoharvest on boot. Where else should I look?
2016-02-17 14:01:37.689 SEVERE e[0;31msomething really bad happened: java.util.concurrent.CompletionException: org.nem.core.node.InvalidNodeEndpointException: host is unknowne[0m (org.nem.nis.NisMain b)
I would say something must have changed ^^ Check config.properties and peers-config_mainnet.json, really untouched?
I have restart from scratch, disable iptables, still get same message. Only change I can think is with the machine, from 4cpu decrease to 1cpu…
spec
1cpu, 1gb ram, 25gb hdd
Look like 1cpu not enough. ssh / ftp won’t response also. 
1 cpu or more has nothing to do with the error you above i think.
Can you supply the 2 files i mentioned above?
Where is peers-config_mainnet.json located? 
Java version
opt]# java -version
java version "1.8.0_45"
Java™ SE Runtime Environment (build 1.8.0_45-b14)
Java HotSpot™ 64-Bit Server VM (build 25.45-b02, mixed mode)
hmm…seems that it is only supplied in the nis jar, so forget it ^^
That leaves only the config.properties as cause of trouble which should be in the NIS folder.
Btw. your java version is rather old 
Upgraded java and reinstalled everything again. Seems to be working now. 
Probably something corrupted when shutdown previously.
Hello
My NIS has not crashed but after about 38 days went under heavy load.
I mean my Ubuntu 14.04 VPS cpu is under heavy load right now.
Here are my cpu info:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
Byte Order: Little Endian
CPU(s): 8
Vendor ID: AuthenticAMD
CPU family: 21
Model: 0
Stepping: 2
CPU MHz: 2800.000
BogoMIPS: 5600.00
Hypervisor vendor: VMware
Virtualization type: full
The server has 2GB memory
I see NIS is taking about about 170% CPU
This is 2 core processor.
Is the NEM network under heavy load lately or what?!
I would simply restart NIS. The network is surely not under heavy load.
I had the same on my server. Same configuration (VPS Server) as freigeist. A restart of NIS and it was solved.
I have done it! It works now for 2 days without problems.
Thanks.
