1,0 TB HDD sata
250 GD HDD sata

Can anyone help me with this problem? or suggest some login tool so I find out what is happening?
 
They should (when in the same subnet as the primary address). Does not explain the hang, but it's good to get the config right to start with.

OP: what is "sometimes during the night"? Same night every week? Same time every night? Anything in logfiles?
 
Does this happen around 3am? You don't have any sendmail running, not even local-submit-only. periodic(8) probably tries to mail but fails. This shouldn't hang the system but perhaps it does fill up a filesystem.
 
Use
Code: 
sendmail_enable="NO"
instead of
Code: 
sendmail_enable="NONE"
Run [cmd=]/etc/rc.d/sendmail start[/cmd], and make sure your root email is aliased somewhere (or read your root mailbox every day).

That way you will at least see any errors your system reports when running daily/weekly jobs (periodic(8)).
 
I had this same type of problem on one of my slackware boxes running as a video surveillance server. Turned out that one of the disks in the software RAID-0 had bad sectors and slocate (I think) when it scanned the file system to build a database of files would take the system down when it hit that spot. I found it by an fsck of the RAID and then calculated out which drive it was on, but it was something that had me confused at first.
 
Well, the op should tell us what his system is doing every night. It isnt that easy to read in a crystal ball ;).

[Solved] system hanging every night

Thanks everyone.

I didn't reply earlier because I was certain that it had worked.
Has been 2 nights and the system is still working.

What solved the problem was
Code: 
 sendmail_enable="YES"

About other speculations: my system has a brand new power supply no more that 3 days old.

Has I've said, thanks for the help.
