[samba-jp:20128] 書き込み遅延が頻発します

[野口＠不動技研工業]

野口と申します。

現在、Samba＋LDAPでドメインを構築し、ユーザのホームディレクトリに、
FirefoxやThunderbirdのプロファイルを置いて使っています。

この環境にて作業をしていると、Thunderbirdで受信したメール（のファイル）
の読み書き時に、「Windowsの書き込み遅延」警告が頻発し、
ひどい時には送受信出来ない状況になります。

ディスク故障を疑って、ディスクチェック、交換（移行処理）を行ってみたので
すが、問題が解決しません。

最近、太田@NECさまがＭＬへ投稿した「dos filetime resolution」の件を見て、
もしかしてSAMBAのオプションが関係しているのか？と思っているのですが、
何か情報をお持ちの方いらっしゃいませんでしょうか？

念のため、smb.confも添付いたします。
よろしくお願いいたします。
