Meteohub freeze after 12-24h

Meteohub freezes 12-24h after boot.
http gives "404 Not Found. The requested URL '/cgi-bin/meteohub.cgi' was not found on this server." -error.
ftp-uploads wont work, can't get ssh-connections. It seems that it still logs data (not sure)
After reboot it works 12-24h but it wont start recomputation even if I press recomputate-button. Theres "waiting"-text..
I don't know what is wrong and what I should look to find out the problem?

Very odd. Do you have lots of services scheduled that are trigger every minute?
This looks like the system is flooded with tons of computation requests not taking
into account that the RPI is very very poor performer, much closer to the antique
NSLU2 than to any modern ARM platform.

Leuven-template related uploads and five weather-network updates.
I had NSLU2 3 years without problems and now RPi maybe 4-5 months without problems.

Can you please browse to "
http://ip-of-your-meteohub/cgi-bin/help.cgi"?
Then I might be able to login and check.

Done. Is this reverse ssh? Or do I have to open port for you?

It is a reverse ssh tunnel. I can login.
Meteohub log shows:
Code: Select all

So raw data for 2013-09 and 2013-12 contains bad data. I fixed this by using the cleanup features on "inspect data" page.
Doing some more experimentation the system crashed with these messages:
cat: /data/weather/201407/raw: Input/output error
cat: /data/weather/201408/raw:
Input/output error
cat: /data/weather/201409/raw:

cat: /data/weather/201411/raw:

cat: /data/weather/201412/raw:
No such file or directory
/home/meteohub/wmr928fulleval:
cannot create /data/log/meteohub.log: Read-only file system
Which simply speaking means that your file system goes corrupt out of nothing.
This is clear indication of a defective SD card or the RPI having trouble to connect
correctly to the SD card.

ok. I had a usb stick crash 2014-07 and 2013-10. I tried restore data to new system from both sticks..
I have rsync backups on my NAS, do you mean that data is also corrupted? There is data all that time and meteohub is done succesful recomputation many times?
At this moment it's freezed again. I have ssh-connection which is partially working but no ftp or http.. example cat or ls commands not found???
These are all commans I can do for now:
Code: Select all
bg command dirs enable fc help local read shopt trap unset
./ bind compgen disown esac fg history logout readarray source true until
: break complete do eval fi if mapfile readonly suspend type wait
[ builtin compopt done exec for in popd return test typeset while
[[ caller continue echo exit function jobs printf select then ulimit {
]] case coproc elif export getopts kill pushd set time umask }
alias cd declare else false hash let pwd shift times unalias
So, new install to new sd-card?

Definitely a HW problem. I wonder why you are using USB sticks?
Meteohub does run and store on SD cards. Did you do modifications?

Fresh install now and it seems to working.. recomputation is completed and system data usage is 74% (yesterday it was only 66%)
I did several checks to sd-card and it's fine and working.
