[jira] [Updated] (JAMES-3941) NPE with health checks

[vincent PIRAT (Jira)]

     [ 
https://issues.apache.org/jira/browse/JAMES-3941?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
 ]

vincent PIRAT updated JAMES-3941:
---------------------------------
    Description: 
When James is installed on an EC2 instance behind a Network loadbalancer, it 
looks like health checks are generating NPE when James tries to retrieve IP 
info from the connection.
Does not seem to have functional impact but generates lot of noise.
James is configured with 2 open ports (143 for Imap and 465 for Smtp).

  was:
When James is installed on an EC2 instance behind a Network loadbalancer, it 
looks like health checks are generating NPE when James tries to retrieve IP 
info from the connection.
Does not seem to have function impact but generates lot of noise.
James is configured with 2 open ports (143 for Imap and 465 for Smtp).

>             Project: James Server
>          Issue Type: Bug
>          Components: app
>    Affects Versions: 3.8.0
>         Environment: AWS
>            Reporter: vincent PIRAT
>            Priority: Minor
>
> When James is installed on an EC2 instance behind a Network loadbalancer, it 
> looks like health checks are generating NPE when James tries to retrieve IP 
> info from the connection.
> Does not seem to have functional impact but generates lot of noise.
> James is configured with 2 open ports (143 for Imap and 465 for Smtp).
