Some probems...

[BlackCat]

I have installed Porteus Kiosk [with chrome] in 30 computer in same network, with different CPU, motherboard, etc...

For now in 2 of them some times the system freeze and it's not possible even reboot it from ssh, only thing that it's possibile do it's a manual reboot with the power button.
Some times the session reboot automatically after timeout. Every time it's possibile move the mouse but nothing more than this.

The only "common" thing with these 2 computer it's the hardware, so i think that it's possible, a compatibility problem, right ?

These are the resoults of /proc/cpuinfo and lspci

I need to know this beacuse i have 3 computer with same configuration and we have to add more...so if i have to exclude certain hardware... it's very important for buy the correct one...

Hi BlackCat,

1) I understand that 28 kiosks works ok and only 2 are freezing?
2) Are you using these kiosks for digital signage (working non stop 24h/day)?
3) Please provide debug report from each PC model which freezes.
4) Please enable full persistence for system logs:

Code: Select all

persistence=/var/log

and send /var/log/messages file to [email protected] when freeze occurs (few times would be the best).

If you can move the mouse then probably only Chrome hangs (could be memory leak). You may try switching to Firefox and check if that helps.

Thank you.

[BlackCat]

Yes for now only 2 of them. Both with same hardware.

They are not used as digital signage but they are online for more than 16 hour every day.

I can't enable persistence beacuse a request for the system it's not save anything for privacy purposes.

[BlackCat]

If i add to remote configuration the parameter

Code: Select all

persistence=/var/log

When after the test i remove it, the old log was destroyed or the log made until the remove of this settings are salved on the hard drive ?

It's really important that the log aren't keep on the disk after the tests.

[fanthom]

Yes - the log is kept on the hard drive.

If you want to clear it then use this:

Code: Select all

run_command=mount /dev/sda4 /mnt; rm -r /mnt/*; umount /mnt

Replace 'sda4' with correct drive letter.

[BlackCat]

how i can do this with remote configuration ?

And with this command i erase entire sda4, not only the logs...

I am confused.

[fanthom]

"how i can do this with remote configuration ?"
I have provided you a parameter. Just add it to your remote config.

"And with this command i erase entire sda4, not only the logs..."
Use this:

Code: Select all

run_command=mount /dev/sda4 /mnt; rm -r /mnt/var; umount /mnt

[BlackCat]

OK very well, thanks !

Sorry for misunderstanding.

As soon as possible i try them
