two days ago I set up my FreeNas on an old computer. The setup contains of two 3TB HDDs, mirrored. I enabled FTP and started uploading 300gb of data over the night. The next day I tried to reach the webinterface or ping the FreeNas server it almost didn t sent the packets back or responden first after the 6th time. The Webinterface was very^100 slow. And when the interface finally loaded it took another 2 minutes til the sidebars was loaded. Then I restarted the Nas and everything worked quite well again. The next night I tried the same preseature again and the same thing happen.
