Out Of Memory freeze

[koper89]

Hi,
I have a problem with xbian freezing on out of memory, I got working rtorrent + sickrage, but when it's trying to download 2+ files - my raspberry keeps freezing on RPI1 like here:
http://forum.xbian.org/printthread.php?tid=2693
on RPI2 without saying anything.
I suspected it may be out of memory casue i installed syslog and here's output before freeze:

Then it's freeze.

I suspect it may be because my swap is really small:

Terminal

root@xbian /var/log # free -m
total used free shared buffers cached
Mem: 738 243 494 0 2 144
-/+ buffers/cache: 97 640
Swap: 82 0 82

Terminal

root@xbian /var/log # swapon -s
Filename Type Size Used Priority
/dev/mmcblk0p3 partition 84988 0 0

I'm running it from usb harddrive, here's my cmdline.txt

Terminal

telnet zswap.enabled=1 zswap.compressor=lz4 partswap sdhci-bcm2708.sync_after_dma=0 dwc_otg.lpm_enable=0 console=tty1 root=LABEL=xbian-copy rootflags=subvol=root/@,thread_pool=2,autodefrag,compress=lz4,commit=120 rootfstype=btrfs rootwait smsc95xx.turbo_mode=N logo.nologo quiet noswap loglevel=0 mod_scsi.scan=sync partswap startevent=mountall splash nohdparm --startup-event mountall
