<div>Hi Markus,</div>
<div> </div>
<div>Thanks for the tips. In fact I made a mistake, because I thought that with "-m 4096" I was setting 4GB of memory, and unfortunatelly I not payed attention on memory=4096. Anyway, I tryed with both your suggestions (with and without -m memory=4096" and still ger error:</div>
