Hi,

Please subscribe to the mailing list for faster answers.

What is the value of {{socketTimeout}} ?
I can see in your configuration that you let the default value for
maxConnectionsPerHost which is 20. When the problem occurs, do you have a
lot of users on the application? How many hits/s? Does the problem fix
itself when the load decreases or not?
Is EsiGate used also for static files (images, js, css) from the drupal
backend? If so why did you disable the cache.
