    Nope. Same issue every few days and still on 14.x but I cant imagine that this is a bug and will be fixed with 15.x 

    I think the messages doesnt come from the application I suspect rather a other one. How can I track this? Some fancy iRule to log this big XML requests? I can imagine that this is coming from a total different application where Im not informed about xml/soap requests.

        when HTTP_REQUEST {
    #Check if the request is a POST, with a content type of text and size over 10MB
    if {[HTTP::has_responded]} {
        return
    }
elseif {[HTTP::method] eq "POST"}{
	if {[HTTP::header value "Content-Type"] contains "xml" or [HTTP::header value "Content-Type"] contains "json"}{
	if {[HTTP::header value "Content-Length"] >= 10000000}{
    log local0. "This is the HTTP Path: [HTTP::path]"
    log local0. "Client [IP::client_addr] This is the HTTP Host [HTTP::host]"
    log local0. "Client [IP::client_addr] accessed [virtual]"
    log local0. "Query string of URI: [HTTP::uri] is [URI::query [HTTP::uri]]"
    log local0. "HTTP Content Length Header = [HTTP::header value "content-length"]"
    log local0. "HTTP Content Type Header = [HTTP::header value "content-type"]"
}
}
}
