NAS 104 locking up

Good thing I found this thread because I was about to return mine! I've only had it for about 5 days and it was being insanely slow when trying to transfer movies and tv shows from my pc to the NAS, it didn't matter if it was via NFS, SMB, FTP or RSYNC. It has crashed on me about 6 times already and as a previous poster stated the only way to revive it is to pull the plug. It just kept on saying that it lost the connection and I thought my router was the problem since I constantly have problems with it but it is most likely the DLNA daemon (along with the swappiness setting, but my RAM is usually around 350 MB used) since I was/am copying terabytes of data. I got pissed off and deleted most of it because after constantly transferring for two days it wasn't even done so I just said "F*** it!" and wiped the drive and put it in the NAS, which automatically set it to RAID1 which kind of annoyed me (would rather it be in RAID0 until I get my two other drives and can put it in RAID 5 or 10). I'm downloading stuff with SABnzbd and the CPU is always pegged at 100% and the temperature is around 150F. I'm at work now and can't test this out because surprise surprise the damn thing crashed again and I can't SSH or use the ReadyNAS remote to get in.

edit: this didn't help. I changed swappiness to 60 and DLNA isn't enabled. I left it on over night to copy files over and then had SAB auto-resume after it was done copying the files. I woke up 6 hours after I had started this to find that everything was still working (but really slowly) and that it had actually swapped out data from the RAM...but then it proceeded to crash constantly after I started interfacing with it.
