Es kann einen Hobby-Administrator an den Rand des Wahnsinns treiben, wenn jede ankommende Mail das gut gepflegte Linux-System in die Knie zwingt, als ob man hunderte von Emails zu empfangen h\u00e4tte. Die Ursache kann eine Kombination aus cyrus und postfix sein…<\/p>\n

Wie eine Diskussion im ServerSupport-Forum beweist<\/a> bin ich nicht das einzige Opfer eines geizigen Hosters. Es trifft vir allem die Benutzer von Postfix<\/a> und Cyrus<\/a>. Postfix legt schon beim start einige Sockets an und Cyrus schaut sich die ganzen Mail-Verzeichnisse der Banutzer (+ einen Index als berkley-Datenbank) an. Jedes Programm braucht nat\u00fcrlich einige Bibliotheken, um \u00fcberhaupt zu starten: so z. B. openssl-Bibliotheken f\u00fcr SSL- bzw. TLS-Verbindungen. Apache und MySQL brauchen auch einiges. Mit\u00a0\u00a0\u00a0\u00a0 [code] lsof | grep -c -e „.*“[\/code] verr\u00e4t, wieviele davon im System offen sind.

\nNach langer Suche fand ich in dem bereits genannten Forum eine Antwort auf meine Fragen (wie: warum ulimit-Aufrufe nichts ausrichten k\u00f6nnen). Der Hoster hat einen viel zu niedrigen Wert in der virtuozzo-Konfiguration angegeben. Herausfinden kann man das mit [code] cat \/proc\/user_beancounters [\/code]
\nWenn das Ergebnis von lsof nicht weit von numfile-Werten entfernt ist, wissen wir, was los ist. Unser Hoster ist zu geizig und macht den Betrieb unm\u00f6glich – vielleicht ein weiterer Grund, um ihm mit K\u00fcndigung zu drohen!
