Hi, i'm trying to write into a file from a thread, but i get

5052 Warn  bluebat.client.communication -
<communication address="00:1D:6E:9D:3C:CD" protocol="rfcomm" port="1">hello!</communication>
Segmentation fault

This is the code (only the useful one):

File output;
Mutex mutexout;
Document!(char) doc;
DocPrinter!(char) docprint;

static this(){
	output = new File("data.xml", File.WriteCreate);
	mutexout = new Mutex();
	doc = new Document!(char);
	docprint = new DocPrinter!(char);
}


int process_client(Communication client, char[] protocol, int port){
	auto logger = Log.lookup("bluebat.client.communication");
	logger.level = logger.Info;
	logger.add(new AppendFile("log.txt"));
	logger.add(new AppendConsole());
	
	
	mutexout.lock();
	
	doc.tree.element(null, "communication", cast(char[])client.Receive)
    .attribute(null, "address", client.GetAddr)
    .attribute(null, "protocol", protocol)
    .attribute(null, "port", Integer.toString(port));
	logger.warn(docprint(doc));
	output.write(docprint(doc));
	
	Stdout("FINISHED").newline;
	mutexout.unlock();
	
	
	
	return 0;
}

When "output.write(docprint(doc));" is executed it dsegfaults. The "process_client" function is called from a thread of the ThreadPool?.

Does anyone know how to solve this issue? thanks

Solved, it was that i called output.close() somewhere in my code and then i tried to write in it.

This happens when you code at 2 AM :)

See you
