saturation of disk
 

I have a problem with the disk saturation because of temporary file and log files.
Is there a solution for this situation?:(

Is 'saturation' anything like 'filling', or is it more like 'using all the bandwidth' (saturating the interface)?

If you mean that your /tmp folder is getting filled with log files,
it is probably because there's something running that is doing that.


You can increase your tmp partition, if it is separated.

But I would check first which is the process that is filling up the /tmp folder.

If the disk is filling up, first find out which files it is, which will tell you which program(s) to check.
Tell us which distro+version you have
Most (all?) will have a tool called logrotate http://linux.die.net/man/8/logrotate, usually configured in /etc/logrotate.d, which will automatically cleanup your logs, depending on the cfg.
