Please help! Login failed

I rebooted my box this morning (RHEL5.8, 64 bit) and tied to log in as a regular user, but got this message:

GDM could not write to your authorization file. This could mean that you are out of disk space or that your home directory could not be opened for writing. In any case, it is not possible to log in. Please contact your system administrator.

When I log in as root, my user home directory has plenty of space (>1TB out of >2TB), it can be opened and accessed. I can login from the command line
su - yaximik
and this puts me into my home directory.

Please help to identify and fix the problem.

So it looks like /tmp is full, but why user login is affected but not root login? My tmp directory (home/yaximik/tmp) is actually very small (164 KB).
Content of the /tmp:

Can someone pls advise what can be safely deleted?

[SOLVED] Please help! Login failed

The /tmp directory contained a 127GB chunk of a database backup file that was created just prior the problem happened, which filled it up. After deleting it everything is back to normal. Thanks for help!

The question still remains - why user login, but not root login is affected afer filling up /tmp?

The reason for this lies deep in the usage of /tmp, why it is created and how it has a significant role in the file system hierarchy.

IT contains various files those are temporarily generated for being used by programs to run. root is independent but not normal users they need a place to write their temp data and hence results in login failure when they are not able to do that.
