Linux ゲートウェイで IGK open_tcp_server エラーが発生 - F-Secure Community

質問

Linux ゲートウェイで open_tcp_server エラーが大量に発生しました。

回答

上位ルータ、あるいはネットワーク等に問題があった場合このような現象が発生致します。
本ケースでは TCP フィルター処理の上限を超えたため、8000 セッション以上のセッションが破棄されていました。

基本的には診断情報より個別に製品の動作を確認させて頂きますが、下記ワークアラウンドで回避できたケースも御座いました。

【ワークアラウンド】
/opt/f-secure/fsigk/conf/fsigk.ini
内の [http] セクションに以下行を追加
timeout_inactive=yes

その後、インパクトの少ない時間帯に、以下手順でサービスのリスタート

Linux ゲートウェイ 5.x の場合 (インストール先を変更していないデフォルト設定の場合)

# cd /opt/f-secure/fsigk

# make restart
