Transmission crash every few minutes

[fasolens]

Hi there,
I'm using Raspberry Pi as my home media center. I have installed transmission daemon to download. Every few minutes transmission appears to be down and I have to enter $this->bbcode_second_pass_code('', 'systemctl enable transmission') to start it again.
It there any way to check what happens with transmission and why it became down?

[moonman]

run it manually in foreground to see the errors:
$this->bbcode_second_pass_code('', 'transmission-daemon -f')

I started it manually

there is what I got on console:
$this->bbcode_second_pass_code('', '
[09:19:04.073] UDP Failed to set receive buffer: requested 4194304, got 344064 (tr-udp.c:78)
[09:19:04.075] UDP Failed to set send buffer: requested 1048576, got 344064 (tr-udp.c:89)
Killed
')

I have no idea why it was killed. How can I check this?

[moonman]

it might have been consuming too much memory. How much ram you have assigned for GPU in config.txt?

[fasolens]

Where can I find config.txt file?
I have Pi with 256MB of RAM

Earlier I had Debian installed on it and never had this problem.

I found config.txt file.

I had such configuration connecteg with gpu:
$this->bbcode_second_pass_code('', '
gpu_mem_512=316
gpu_mem_256=128
cma_lwm=16
cma_hwm=32
cma_offline_start=16
')

Using swap?

[fasolens]

No. And on my previous Debian system Pi worked also without swap. Is it better to enable it in 256mb version?

I left 64mb for GPU, I don't use HDMI output so I suppose 64mb is enough. Now transmission works without issues.
