@IrekSw,

it might be a resources issue. How many node does your graph contains? How many CPU cores have to attached to the VM?

Hi,

I have 2 CPU, i can't login via www to minemeld and check numbers of nodes, there is another way to check the number of nodes?

Re: minemeld-engine FATAL Exited too quickly (process log may have details)

@IrekSw: The configuration should be at /opt/minemeld/local/config . You can grab the number of nodes from there.

If I count well, I have 99 nodes.

@IrekSw: 99 nodes might be too much for a dual core system. I suggest you to add additional cores. MineMeld will take are of distributing the nodes between cores.

Is it possible to delete some mods without access via www?

Re: minemeld-engine FATAL Exited too quickly (process log may have details)

xhoms — Thu, 01 Feb 2018 09:26:44 GMT

@IrekSw,

yes. Just edit /opt/minemeld/config/running-config.yml with your favorite YAML editor. Once it is ready, copy it over /opt/minemeld/config/committed-config.yml and then restart the engine.

I'd try a service restart:

sudo service minemeld restart

If, after that, service is not running then I'd take a look to the web logs (/opt/minemeld/log/minemeld-web.log)

@IrekSw,

MineMeld depends on a in-memory database called "Redis". In your system the "redis-server" service seems to be down.

Try:

sudo service redis-server stop
sudo service redis-server start

Hi,

After to add some new nodes, I've get ENGINE FATAL ERROR and i don't know how to resolve this error. I mean, I've deleted some nodes from running conf and copied it to commited file and nothing. The error is:

[2019-12-09 12:27:01 UTC] [2641] [ERROR] Error retrieving childen of 0
Traceback (most recent call last):
File "/opt/minemeld/engine/core/minemeld/flask/supervisorapi.py", line 97, in service_status

raise NoSuchProcess(pid, None, msg)

Please, help with this to keep working with Minemeld, because it's not the first time I reinstall the instance to keep working this this platform.

Thanks
