httpd' on server suddenly stop

SeLLeRoNe

But I must find a solution to this problem!
I can not now add a new domain or to delete the domain because the httpd stops working
Sometimes stops suddenly for no reason .

Yesterday, minutes before I go to sleep suddenly stopped!
so I Left sleeping and searched hours for a solution to no avail.

but now apache is working correctly or not?
Click to expand...

SeLLeRoNe now is working correctly , but the problem that i dont know when the next time it will stop!
after i stopped it before 5 minutes i check and there is nothing use pot 80/443
 
thats why im asking, those command you are doing right now are useless if apache is working.. those are useful command for understand what is going wrong when apache dont start
 
so what you think happen here?
i think that :
clamav
or
something wrong with apache conf.file
or
some thing with dns
 
this is the error log of apache when it stopped work at first time:
all start when i add this domain : www.newmsr.com

@asishlla,

You're short of free space in /var partition:

That's might be the reason. Probably the partition is too small, or you need tune rotation periods for logs.

Post results of:

Code: 
df -h

Anyway, it would be usefull to see result for:

Code: 
df -i
df -h

please:
Code: 
[root@server ~]# df -i
Filesystem            Inodes   IUsed   IFree IUse% Mounted on
/dev/sda1            120684544 1219661 119464883    2% /
/dev/sdb1            122126336      11 122126325    1% /second
tmpfs                 210631       1  210630    1% /dev/shm
//10.0.5.8/IS-13737        0       0       0    -  /home/admin/admin_backups/nas

Code: 
[root@server ~]# df -h

/dev/sda1             446G   62G  362G  15% /

tmpfs                 4.0G     0  4.0G   0% /dev/shm
//10.0.5.8/IS-13737    50G   11G   40G  22% /home/admin/admin_backups/nas
 
So, that's results in normal situation. Are they the same in the moment, when apache stops and does not start? Did you get any warnings or notifications on email saying, that no free space left? Do you use any graphical monitoring software (like munin)?

after the httpd stop , i try to start or restart it from directadmin or root without Success
just reboot make system up again!

that happen always when i :
1) add new user\domain
2) delete user\domain
3) without reasons\suddenly
4) restore user

note: this thing was happen to me on the old server!
look because of this I purchased a big server, but Unfortunately that not helpped me.

the jost company till me that i should format the second disk before use it!
but i dont know if the guy which install all are do that or not.

i think i have no problem with my server Except this problem!
 
Ok, I really do not know, what you are using on your server and how your scripts work. But with server reboot in normal situation all temporary files are supposed to be deleted.

So I would suppose (since you're using one partition, that is strongly not recommended), that in /tmp or any other temporary directory big files manage to take all available space and that's the reason. It might be temporary MySQL's files or ImageMagick, etc.

So if I were you, I would install munin (installation is very simple and graphs are rather informative) and monitor it.
