Hi,

I have this really strange problem... I have a script, which is started
by cron every 5 minutes and which logs the data of some
temperature-sensors to a mysql-database. It does this for 5 sensors.

Now the strange thing: When I look at the tables, the data from 4 of 5
sensors isn't written to their tables, but only in the time from 9.30am
to 12.30pm. The first sensor's data is written correctly all the time.

Now the other strange thing: I look at my syslog:
Feb 9 12:05:03 helium /USR/SBIN/CRON[433]: (root) CMD
(/var/www/wetter/update.php >> /tmp/1wireerrors.log)
Feb 9 12:05:10 helium mysqld[9934]: 080209 12:05:10 [ERROR]
/usr/sbin/mysqld: Disk is full writing '/var/log/mysql/mysql-bin.000001'
(Errcode: 28). Waiting for someone to free space... Retry in 60 secs

It says disk is full, but /var/log/mysql is on the /var partition which
has 6.4GB free (according to df).


Can anyone me please? I don't see where the error is and why it's
only occurring for 3 hours in the morning. Thank you.
