Error in cannot read /lib/apps/web-index.lua at line I/O error

Hi
This morning I've got that message when I was trying to access my /apps/ folder. What's going on?
Error in cannot read /lib/apps/web-index.lua at line I/O error

Visu works with no problem.

Can I solve it somehow?

Hi, when I started to experience similar problems in various scripts, it turns out that my SD card had reached its life limit, so I had to replace it, restore a backup and then the issues gone away...

Unfortunately I don't have physical access to the device. Is it possible to restart it remotely? Or by KNX bus?

OK, the device has been reset and now it looks OK.
What SD card do I need? Do you have a suggestion?

I see this in my system log:

What's on /dev/mmcblk0p3 ?
Is it OK it's been mounted as ro only and not remounted?

LM team, can you provide me please the actual SD card image for my device for download? I'm afraid these links are obsolete and for different CPUs http://openrb.com/reflash-logicmachine3-...-software/

Thank you

I'm looking for SLC microSD. Does it exist? I can't find any.

Thank you. I was looking for Samsung or Transcend because these two brands were recommended by LM. Is ATP OK too? Is 4GB enough? I thought LM5LP contains 8GB SD.

Even 1GB is more than enough, but the recovery image is made for 4GB cards if I remember correctly.
