Was bedeutet diese Fehlermeldung?


#1

Hallo,

mein owncloud läuft ohne für mich erkennbare Probleme. Gleichzeitig sehe ich im log immer wieder diese Fehlermeldung:

Exception: {"Message":"HTTP\/1.1 412 An If-Match header was specified, but none of the specified the ETags matched.","Exception":"Sabre\DAV\Exception\PreconditionFailed","Code":0,"Trace":"#0 \/var\/www\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Server.php(454): Sabre\DAV\Server->checkPreconditions(Object(Sabre\HTTP\Request), Object(Sabre\HTTP\Response))\n#1 \/var\/www\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Server.php(248): Sabre\DAV\Server->invokeMethod(Object(Sabre\HTTP\Request), Object(Sabre\HTTP\Response))\n#2 \/var\/www\/owncloud\/apps\/dav\/appinfo\/v1\/carddav.php(82): Sabre\DAV\Server->exec()\n#3 \/var\/www\/owncloud\/remote.php(164): require_once('\/var\/www\/ownclo...')\n#4 {main}","File":"\/var\/www\/owncloud\/3rdparty\/sabre\/dav\/lib\/DAV\/Server.php","Line":1267,"User":"my_username"}

Was sollte mir diese Fehlermdeldung sagen?

Wie bekomme ich sie weg?
