server goes down

today when I was logged in from the shell I tried to stop apache service
and the server just stopped responding! this is what I did

-(02:11 15 AM)-(root@server)-(/home) $ service httpd stop
Stopping httpd: [SSH] ERROR: An existing connection was forcibly closed by the remote host.


can someone please tell me why is this? sometimes my server stops responding for no
reason, so I have to open a ticket and request a reboot! could it be because of stopping apache?

Take precautions against static electricity: wear your wriststrap if you have one else ty to toucg the metalwork of the computer chassis as much of the time as practicable and certainly just before you start.

What are the contents of ur /var/log/messages ?
SabrinAuthor Commented:
the server went down at 2:11am
and I see this from the file /var/log/messages

Nov 26 22:08:23 dedicated sysctl: kernel.sysrq = 0
Nov 26 22:08:23 dedicated sysctl: kernel.core_uses_pid = 1
Nov 26 22:08:23 dedicated sysctl: fs.file-max = 65000
Nov 26 22:08:23 dedicated rc.sysinit: Configuring kernel parameters:  succeeded
Nov 27 03:08:24 dedicated date: Mon Nov 27 03:08:24 EST 2006
Nov 27 03:08:24 dedicated rc.sysinit: Setting clock  (localtime): Mon Nov 27 03:08:24 EST 2006 succeeded
Nov 27 03:08:24 dedicated rc.sysinit: Loading default keymap succeeded

so the part from where the server goes down its missing!

May be ur server is exceeding the no. of connection.Please check any entry in /var/log/httpd
Please also check that enough swap memory is alloted by
# free -m
If it not a hack
not a low memory problem
so  I think It because of h/w problems like memory

(I got the same isue in my server and thay (customer support person) told me to clean the memory and now it works fin)e

Also could you check your

/var/log/secure log file for any entries made on that day when your machine stopped responding.
Duncan RoeSoftware DeveloperCommented:
I would check *any* log file in /var/log that has changed recently. Some will be no help, but one may tell you something useful.
SabrinAuthor Commented:
ssvl, how do I clean the memory?
SabrinAuthor Commented:
ibu1, what do I look for in /var/log/httpd
Duncan RoeSoftware DeveloperCommented:
In the absence of an answer yet from ssvl, "re-seating" the memory may help, that may be the same thing as "clean" or may not. In other words, unplug & plug back in the memory sticks. Be sure they are firmly home. Once should be enough, if indeed this is the problem.
Duncan RoeSoftware DeveloperCommented:
toucg should be touch

the datacenter is 100 miles away from where I am..
Duncan RoeSoftware DeveloperCommented:
If it *is* a hardware problem, you'd have to physically fix it even if the system was at the North Pole. Pursue software possibilities first.
