2つのメソッドでサービスを公開するWCFnet.tcpサーバーがあります。
string Get(location);
void Put(location);
maxConnectionsに設定されint.MaxValueます。クライアント側でmaxConnectionsは、800に設定されています。サーバーで例外は発生しません
クライアントアプリケーションがあり、100以上のスレッドが作成されることがあり、各スレッドはいつでもサーバーに接続できます。
スレッドがコネクタクラスを共有している場合、アプリは正常に動作します。各スレッドに独自のコネクタを作成させる場合、20〜30のスレッドを使用すると、各スレッドは正常に機能します。しかし、アプリが50以上のスレッドを作成すると、すべての接続が突然タイムアウトし始めます。

WCFクラスでそのようなことが起こっていることに気付いたのはこれが初めてではありません。
これはWCFの厳しい制限ですか、それともこの動作を取り除くために変更できる設定がありますか？
