Java Error

Blynk Servers Local Blynk Server

Hi All
This is my first time using a local server. Java is throwing lots of errors but the server seems to be up and running but very slow.

This is the error log.

Can someone help?

Hello. Do you have some specific properties? What version of server do you have?

3

Hi

No special properties at all. I have tried it with and without the generic properties file and get the same result. I’m running server-0.21.7.jar

I’m also running:
openjdk version “1.8.0_112”
OpenJDK Runtime Environment (build 1.8.0_112-b16)
OpenJDK 64-Bit Server VM (build 25.112-b16, mixed mode)

Please create server.properties in same folder with jar with :

enable.raw.data.store=false

Does that help?

5

sorry, should be

enable.raw.data.store=false

That fixed the problem.

Thanks for your assistance.

FYI. I am running the server in a FreeNAS Jail. Jail version FreeBSD 9.3. So you can add that to the list of successful installs.

I ran out of things to try so eventually ‘moved’ the blynk server to my Paspberry Pi.

It was a bit of a mission getting everything moved to a new system. Basically has to start from scratch and recreate users and give all of my devices new token ect. I’m sure there is a better way to move servers but could not figure it out.

I still have a problem accessing the admin panel remotely but I thing that is related to SSL under the new Jessie version. Nice thing about Jessie, it come with Java pre loaded.

well, now everything works as expected.

I think the root of my problem has to do with the OpenJDK running in a FreeNAS Jail (FreeBSD).
