From f37d6637f054c8037d11bdf9d1eea1b52069f634 Mon Sep 17 00:00:00 2001 From: Georg Gadinger Date: Mon, 25 Sep 2023 21:02:09 +0200 Subject: [PATCH] Fix "Too many open files" errors when using ElasticSearch This change sets the Faraday adapter used for ElasticSearch to `:net_http`. The `elasticsearch-transport` gem tries to auto detect a suitable Faraday adapter. Mastodon uses the Faraday default adapter of `:net_http`, but since `elasticsearch-transport` sees that the `httpclient` gem is available it lets Faraday use that one. Unfortunately `httpclient` does not properly clean up its connections, leading to a lot of established connections to ElasticSearch over time.
