Dietpi starts hanging

[kami]

Hi,

i am running on an odriod C2 the dietpi image. Really often unter LXDE Screen i can move the mouse and change windows, but in the background for example if i untar a big file it stops and hangs in the terminal. No reaction nothing. After some minutes it goes on. The Tar-command just hangs. Why is this happening. What can i do?

Thanks a lot.

Hi Kami,

Sounds like possible system instability due to hardware.

Please can you confirm:
- SD/EMMC card used (eg: sandisk ultra)
- PSU used (eg: 5V 1A)
- Size of TAR file
- Size of swapfile: /DietPi/dietpi/func/dietpi-set_dphys-swapfile

Hi i am using an SD Card from Sandisk, a standard PSU (is there an output if the odroid gets enough power?)
Tar is like 80MB and swap is 331MB

Thanks a lot kami

Check to ensure that power is above 5vdc

Any time I had flaky RPi usage...it was due to flaky or chincy USB power cables

Hi,

just double checked everything and it was the power cable.

Now everything works fine.

Thanks a lot.

Hi,

i just have to reopen this thread. The Problem comes back. The Power supply is now good enough. Odroid C2 with 2,4A Power Supplay and Dietpi 6.7 Image. I have tested the SD Card with h2testw no write/read error.

But for example if i use the TAB key or try to run "top" or "htop" it keeps hanging like it is waiting for anything. I cannot see anything in the logs and the CPU temp is at 48-52 °C. I hope this is normal. CPU usage is not full but the command just hangs.

Can someone help how to find out where the error is?

Thanks a lot.
