For the last week, my vps (directadmin on centos on xen) has become unresponsive every three days at approximately 5 AM, and I'm baffled about why. It doesn't crash, but it stops accepting incoming connections until it's rebooted.
I'm not sure how to troubleshoot this. /var/log/messages gives no useful information. There are no unusual cronjobs running at that time.
Anyone heard of anything like this before or have any advice about how to troubleshoot?
I moved from shared host to VPS a few days back. Since the move, the site becomes slow during particular time of the day. It appeared to be an issue of cron run by their another client and after promising that they would move that client to another node (I have spent more than 25 days to follow up on this till now) they backed off from their words but informed me about an alternative. Now, they say that the cron of that client was executing many scripts and they have spaced those scripts.
I am looking for a long-term host and was wondering:
1. VPS provides a minimum guaranteed stuff so what is the use of that guarantee if one client can make the server crawl (imagine 5 minutes or more to open a site).
2. Can a host be trusted who does not honour words.
So I've set everything up manually a few times before now, but I got so bored of configuring everything for a manual install I just said screw it and used XAMPP this time - so my circumstances are not completely ideal.
Basically what I am looking to find out is how to improve loading speeds for Apache, PHP and MySQL on my dedi server?
The server I have is of the following spec: Intel Xeon CPU E5-1650 V2 (3.50Ghz with 12 cores total) 64 GB DDR3 ECC 2 x 2TB SATA3 (RAID 0/1)
use Windows Web 2008 R2 so only 32GB of the RAM is usable.
With all the abive aside, here is the important part: Whilst people are browsing the websites I have configured they are random hit with a blank white page saying "Your request has timed out. Please retry the request." - I have about 100 unique hits daily and a lot of people report the same problem, and I have even had it myself.
It feels as if the server has much more power than Apache and co. is trying to utilize - what can I do?
I have configure my Apache to create rotated logs for every periodic time. It worked fine with my local PC, but when it is being configured on to a server system, the actual error.log file is not being update, only the rotated logs are created. If i remove the Error Log command from httpd.conf for Error Log Rotation, again it works fine as usual.
When I type a command with putty, the connection is closed immediately. I tried shutdown-r now and reboot, halt, do nothing to console closes and nothing happens.
After a hundred connection, I can use ls, su and kill.
I think it's the fact that the partition is corrupted. I can not Hardware reboot the server because CTN1 is "out of business".
VPS isn't rebooting by itself when it goes down. Anyone has any program/script that monitors heartbeat of the server? Like when it goes down, the program will automatically reboots the system. I know there's such a script out there but I forgot what it called.
I had to reboot my server and about 20 minutes later I tried to access the web site but the page was not found... I am able to login to SSH. However, I am not familiar with *nix or the workings of CPanel... What should I do to get the sites back online?
so my server dies every day and requires human intervention to fully restart all service to have my site work properly. i suspect sigterm issues as it fails to restart all service as website is still down so i always have to reboot it.

I'm finding that my server doesn't like to reboot gracefully. Either selecting "graceful server reboot" in WHM or actually typing "reboot" in SSH, which then tells me the server is shutting down. My server is then incommunicato indefinitely until I actually do a hard reset remotely.
Is this common? Is there some way to find out why this is happening?
So I was trying to run a backup process in Plesk 8.1 and the whole panel froze up on me (it's happened numerous times before).
Anyway, since the panel was all frozen up I just went into SSH and did a simple "reboot" (also, as done before many times). Only problem is, this time after I did the reboot the server never actually came back online... it seems to be locked up or something, I have no idea what.
I called my host and they are looking into it but they have no idea what's going on either and it's taking them forever to figure it out all the meanwhile my sites are down.... this isn't good.
Does anyone have any suggestions or advice as to why this could be occuring?
Just a general question regarding the frequency which you all reboot your linux servers.
Mine has been up for 178 days, and is running sweet as a nut (touch wood). I was just wondering if it's worth giving it a reboot anytime soon, or if not, how long to give it before rebooting?
At the moment every time I reboot my server I have to execute: # iptables --flush # iptables --zero
just to be able to access the server. (Though it does allow SSH to access before executing those).
And I figured out that I must do something to /etc/sysconfig/iptables to permanently be able to access the server without those commands after reboot. Right?

We changed our SSH port (for the slight added security that this offers) and updated our CSF config with the new port so that we can accept connections on this port.
We restarted CSF and we could connect successfully on the new port. When the server is rebooted connections are refused on the port until we *RESTART* CSF then it's all good again.
I would think being that we opened the port in CSF's config that on reboot the port would be opened back up but this is not happening and any time the server is rebooted we have to restart the firewall.
Does anybody have any suggestions on how to "fix" this or at least make it so we don't have to manually restart the firewall?
Does anyone have any recommendations for colocation providers in the LA area or recommendations for a PDU that has remote reboot capabilities (small budget, nonprofit organization)? We have a total of 9 servers.
I ordered a leaseweb express server 4 box with windows server 2003 and have been running it, installed some software etc which worked out fine.
Anyways, I wanted to disable tcp/ip filtering which I did and afterwards it prompted me that I would have to reboot the server for the changes to take place, I clicked ok and it rebooted. Now I just can't connect with remote desktop, I tried everything.
I'm guessing it either shut down or didn't reboot properly? I tried sending an email to leaseweb support 2 days ago but still no shadow of any reply..
It says that I can reboot the server using the SSC but when I log in there, I can't really find any reboot option.
I've got an old passivley cooled Pentium II box which I am turning into a silent File/Backup server for our LAN at home. Naturally for stability and performance on old hardware, I am running Linux.
The problem I have is that when you reboot the machine, it ends all processes, unmounts etc as usual, but after that the screen just blacks out and it doesn't go anywhere. I have to physically reboot the machine.
During startup theres a message saying BIOS is earlier than 1999, you should set ACPI=FORCE in Grub. I added this and also tried the noacpi and noacip options to no avail.
Windows ran on this fine before so I don't see why Linux would have an issue.
I have a Centos 5.2 box with Cpanel/WHM. A couple days ago it rebooted.
I checked /var/log/messages and I can see where it rebooted, but I can't find anything that indicates why.
I'm trying to figure out if this is a hardware issue or software issue/crash.
I do have Nagios istalled, and it seems it saved some data right before the server rebooted. Not sure if this is a simple coincidence.

problem on one server with debian, the last month it have a 100% f uptime, but since yesterday automaticly it reboot every 1 hour exactly!
this is a game server , dont have service like httpd , mysql dns , nothing! , I uninstall cron jobs thinking that will solve the problem, but no .....
I install firewall, run rkhunter and chkrootkit, check whell gruop and nothing
logs:
Jan 17 05:20:00 debian -- MARK -- Jan 17 05:40:00 debian -- MARK -- Jan 17 06:00:18 debian syslogd 1.4.1#18: restart. Jan 17 06:00:18 debian kernel: klogd 1.4.1#18, log source = /proc/kmsg started. Jan 17 06:00:18 debian kernel: Bootdata ok (command line is root=/dev/sda1 ro )
I change root password and ssh port but nothing... I think that could be a issue on debian or some exploit cause it, this was happend Suddenly one day to another it is very Strange....
I have an dedicated server 2 x Xeon CPU 3.20GHz (2GB RAM), now 30 minutes ago my admin tryed to make a benchmark test on it and after a period the server was not responding ( SSH or http.. ftp ) we asked DN to reboot the server. After the reboot in Service Status page (WHM) there ware many services down and the load was ~ 45.00 (4 cpus) .. after aprox. 5 - 10 minutes the load has droped:
Server Load 2.61 (4 cpus)
is it normal to have such a higher load 45.00 (4 cpus) after an reboot ? The memory used was 32%.
Is it possible to use a APC remote reboot power strip for a server in a blade?
Like for example, say there are 16 servers in a blade, can you remote reboot them individually?
Because blade servers have only like 3-4 redundant power supplies and I am assuming all the 16 servers are powered by the onboard power supplies in the blade enclosure. So...if thats the case, how is it possible to reboot each individual server?
