starting karaf with ansble

Hello,

If I run karaf manually with the start command, I have no error.
But if I run the start command in a ansible task, I have the following command:

347 [sshd-SshClient[7a4ccb53]-nio2-thread-1] WARN org.apache.sshd.client.session.ClientSessionImpl - Exception caught

Any help would be appreciate, I did check the java version, the karaf version , it seems to be related to ansible but I cannot find out the issue.

Maybe your application needs some environment variables which aren’t set when ansible runs the command.

You can set specific environment variables though - see http://docs.ansible.com/ansible/playbooks_environment.html

I did display the variables when running the
start command and I cannot find out which variable would be a problem.
Any clue ?
Regards

Here are the variables set when the error message is displayed:

Is this an init script? It sounds like it relies on something in the
environment.
Does it start at boot cleanly? If not, that's almost certainly the
issue, you might
find setting some variables explicitly in the init script sorts things out.

Sorry I finally found out the issue was not in the start command and then happens in both ways , manually and with ansible.
Don’t pay attention to this ticket, I will keep searching about the issue but it has no link with an ansible issue.

Thank you for your help,
Regards
