Out Of Memory freeze - koper89 - 9th Mar, 2015 04:24 PM 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: Terminal Mar 7 15:23:10 xbian kernel: <30>[ 24.876932] udevd[1114]: starting version 175 Mar 7 15:23:10 xbian kernel: [ 25.335103] bcm2708_spi bcm2708_spi.0: master is unqueued, this is deprecated Mar 7 15:23:10 xbian kernel: [ 25.335606] bcm2708_spi bcm2708_spi.0: SPI Controller at 0x3f204000 (irq 80) Mar 7 15:23:10 xbian kernel: [ 25.400182] bcm2708_i2c_init_pinmode(1,2) Mar 7 15:23:10 xbian kernel: [ 25.400203] bcm2708_i2c_init_pinmode(1,3) Mar 7 15:23:10 xbian kernel: [ 25.400711] bcm2708_i2c bcm2708_i2c.1: BSC1 Controller at 0x3f804000 (irq 79) (baudrate 100000) Mar 7 15:23:10 xbian kernel: [ 25.572035] smsc95xx 1-1.1:1.0 eth0: link up, 100Mbps, full-duplex, lpa 0x45E1 Mar 7 15:23:10 xbian kernel: [ 25.807001] pcm512x 1-004d: Failed to reset device: -5 Mar 7 15:23:10 xbian kernel: [ 25.807049] pcm512x: probe of 1-004d failed with error -5 Mar 7 15:23:10 xbian kernel: [ 25.807197] pcm512x 1-004c: Failed to reset device: -5 Mar 7 15:23:10 xbian kernel: [ 25.807226] pcm512x: probe of 1-004c failed with error -5 Mar 7 15:23:10 xbian kernel: <12>[ 31.875105] init: failsafe main process (512) killed by TERM signal Mar 7 15:23:10 xbian kernel: <12>[ 35.713325] init: wait-for-state (xbmcxbmc-loaded) main process (1578) killed by TERM signal Mar 7 15:23:10 xbian kernel: <12>[ 42.803300] init: xbmc-failed-start main process (930) killed by TERM signal Mar 7 15:23:10 xbian kernel: <12>[ 42.829024] init: wait-for-state (zram-swapxbmc-done) main process (1275) killed by TERM signal Mar 7 15:23:10 xbian kernel: [ 43.100164] Adding 84988k swap on /dev/mmcblk0p3.

And is there any advantage of swap partition or there's no real difference between swap file and swap partition?

And is there any advantage of swap partition or there's no real difference between swap file and swap partition? I don't known if it can solve, but at least you can exclude out of memory errors. I suggested swap file cause it's the fastest way to add swap space and, if you don't need it anymore, you can easily delete it. RE: Out Of Memory freeze - f1vefour - 9th Mar, 2015 11:47 PM It's not that, it's a bug in the network driver. I am working on it. XBian includes a small swap partition, you can see in the log where it activated it. *edit* Your issue appears to not be XBian related exactly, it's rtorrent misbehaving and bringing down the system with it. RE: Out Of Memory freeze - f1vefour - 10th Mar, 2015 02:36 AM I have a kernel for the RPi 2 I would like you to try.

RE: Out Of Memory freeze - koper89 - 10th Mar, 2015 05:49 AM Already installed, I'll try to stress it tomorrow and post here results Thanks for help! RE: Out Of Memory freeze - f1vefour - 10th Mar, 2015 06:02 AM Thanks, the sooner the better. If it resolves your problem I can push the changes out.

I don't know what to make of this really. I have 50Mbit downstream and it was pulling in about 7 megabytes/sec until it becomes semi-unreponsive. I switched to a USB drive instead of the systems sdcard and it appeared to be worse.

RE: Out Of Memory freeze - koper89 - 10th Mar, 2015 04:16 PM It stopped but i stressed it a lot It seems like it lost time because it's back in past Here are my logs: syslog http://pastebin.com/mbB9LTPg kern.log http://pastebin.com/0zgFe8Hd |
