Hi guys,

I need some help regarding this problem.

Yesterday I upgraded from Wheezy to Jessie. Today I got an email saying the user could not create a "tmp" file to do anything.

I checked the filesystem with:

------------
# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 46G 46G 0 100% /
udev 10M 0 10M 0% /dev
tmpfs 789M 82M 708M 11% /run
tmpfs 2.0G 4.0K 2.0G 1% /dev/shm
tmpfs 5.0M 4.0K 5.0M 1% /run/lock
tmpfs 2.0G 0 2.0G 0% /sys/fs/cgroup
/dev/sda3 864G 4.0G 816G 1% /home
tmpfs 395M 0 395M 0% /run/user/1000
tmpfs 395M 0 395M 0% /run/user/1340
tmpfs 395M 0 395M 0% /run/user/1328
tmpfs 395M 0 395M 0% /run/user/1360

Also tried to find what was using such huge space with:

------------
# find / -xdev -type f -size +200M -exec ls -lh {} \;
-rw-r----- 1 root adm 4.2G Jul 5 16:05 /var/log/messages
-rw-r----- 1 root adm 5.6G Jul 5 16:05 /var/log/kern.log
-rw-r----- 1 root adm 16G Jul 5 16:05 /var/log/syslog
-rw-r----- 1 root adm 9.6G Jul 5 16:05 /var/log/daemon.log
------------

I'm not convinced that only 16G of syslog is my whole problem. But Id start with that, if I can make the system usable again. So I check the log just to see, over and over, this messages:

Ok, I run:

# apt-get remove wpasupplicant

I could break the "while" loop deleting syslog. It stoped spamming. Looks like all messages was linked to it.

I don't know very much wpasupplicant. Ill this software be needed in the near future?

Im afraid the system is working only now, and will be unreachable next reboot.

To keep up with Santiago and Joe:

Santiago, thanks for the file. I do prefer not use if not necessary, though. Lets see how things goes.

Joe, I'm runing this server via ssh. And I cannot turn it off, as there are users online now.

I'll read your other suggestions more easily now that its "kind of " working.

Thanks.

Beco.
