I/O error flushing output to client

Post by bytemare »

Hallo,

vielleicht kann mir mal jemand sagen, wo das Problem zu suchen ist?!?
Irgendwas versucht zu connecten, die Verbindung wird aber unterbrochen? Meine Vermutung!

Code: Select all

Broken Pipe Fehler treten i.d.R. bei Berechtigungsproblemen auf (fehlende Berechtigung auf Verzeichnissen, Partitionen mit nosuid oder noexec gemountet).
“Some humans would do anything to see if it was possible to do it. If you put a large switch in some cave somewhere, with a sign on it saying 'End-of-the-World Switch. PLEASE DO NOT TOUCH', the paint wouldn't even have time to dry.” — Terry Pratchett, Thief of Time

danke, dass wäre schon mal ein ansatz.

das problem besteht erst seit einem upgrade von etch auf lenny - alle dienste funktionieren.

die frage ist also, wer baut die verbindung auf?
welchem verzeichnis fehlen rechte? könnte das evtl. was mit confixx zutun haben?
