アプリケーションpsycopg2 + pgbouncer + geventがあります。非同期アプリケーション。つまり、1 つのプロセスが複数の要求を処理します。データベースへの非同期アクセスは、psycopg2 の最新バージョン (2.2 ではなく) で登場しました。ただ今回のリリースで、pgbouncer からの切断が多発するバグが導入されました。pgbouncer ログに次のエントリがあります。

汚れたサーバーに関するメッセージを回避するために、pgbouncer を設定する方法はあるのでしょうか? 何かを修正するパッチがあるなど、バグに関する情報。ubuntu リポジトリのすべてのパッケージは、運用マシンにパッチを適用します - 良いオプションではありません。私の設定pgboucner：
[pgbouncer]
logfile = /var/log/postgresql/pgbouncer.log
pidfile = /var/run/postgresql/pgbouncer.pid
listen_addr = *
listen_port = 6432
unix_socket_dir = /var/run/postgresql
pool_mode = session
server_reset_query = DISCARD ALL;
server_check_query = select 1
server_check_delay = 10
max_client_conn = 1000
default_pool_size = 200
log_connections = 1
log_disconnections = 1
