/backend_checker (see https://github.com/geoadmin/service-print/blob/master/print3/main.py#L77) seems to abort() on every request. I tried to reproduce manually but was not successful: calling the handler via nginx returns the error:

# curl [ip]:8009/backend_checker
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 3.2 Final//EN">
<title>503 Service Unavailable</title>
<h1>Service Unavailable</h1>
<p>Incomprehensible answer. tomcat is probably not ready yet.</p>

Calling the Tomcat check directly returns the required ok:

# curl [ip]:8011/service-print-main/checker 
OK

This causes all our Load Balancer to consider all targets "unhealthy" (which luckily forces the LB to server all backends).

The text was updated successfully, but these errors were encountered:
