Debian - Directadmin - Weird crash
Please read whole of the post and take your time. The written material is lesser. More are the logs. I've spent more of mine is writing it . I will be thankful to you if you read it and post a helpful reply if you can in any way possible.
I will be specific and will try to explain this in as much details as possible.
I run the latest Debian 5.0.6 Net-Install ( Lenny ) on my Machine with the following specs. The Directadmin and OS both were perfectly and cleanly installed without any errors.
HDD : 10GB
RAM : 3GB
CPU : 2Ghz
I won't call it as a crash . This is what happens:
I usually keep opening my website round the clock and analyze traffic about it . There were problems. The website went inaccessible sometimes . I tried from a lot of Computers but it was all the same.
-> SSH failed but after many tries sometimes worked and got stuck.
-> Control-Panel failed but sometimes logged in and stuck after.
-> On Pinging, sometimes pings were normal but sometimes 4 digits.
On the little access I had to the system, I tried a lot but couldn't configure. Today was Sunday so I stayed on and luckily the problem happened when I was logged in.
The Diagnose and Analysis:
None of the websites were working but as I logged in to SSH, I saw this:
Code:
panel:~# free -m
total used free shared buffers cached
Mem: 3035 2919 116 0 125 325
-/+ buffers/cache: 2469 566

I ran a top:

Now you can see apparently above, no active process is using a lot of RAM, it's just the Buffers/Cache .
During this time I was using SSH, I kept giving tries to Apache status as IP/server-status, Control Panel and websites. None were working.
I ran a top again in 2 mins:

Continued...
I also have a VNC viewer to see the actual console of the server so the same time, I opened it just to see if the system was giving any messages.
When I was using console, it gave me these messages below in Screenshot attachment. But we can ignore these console messages because this was an outcome of what happened, not the problem.
Attachment 1129
External Link : http://www.s4aclan.com/console.JPG
I kept doing everything I could to see whats the cause because I couldn't read everything from the top, ram usage or even what console was showing . Luckily, Apache Status and Control CMD_SHOW_SERVICES opened for me .
Remember : My site on average has 50 people online at every 2 minutes and the site was working fine at that time. Also on viewing the apache status, I could only see 10-20 requests although the traffic was more.
When this problem happened, only 10 people were online but I could see 237 requests in the apache status. I don't know why.
Here is the apache status wrapped:
Code:

On running top again, I saw more apache processes and CPU usage increased to 50% too. Here is the control panel's Processes look:
Attachment 1130
External Link : http://www.s4aclan.com/cmd_show_services.JPG
Someone once told me a command to drop all caches, the command was this :
Code:
panel:~# echo 3 > /proc/sys/vm/drop_caches
Cache is actually the memory which drops itself when the system needs it . Anyhow, I dropped it myself. Free RAM increased from a 100 to 300MB. CPU usage at that time was 50% with apache processes still about 50 in number. But the websites started working although very slow.
Soon after about 20 mins, the RAM dropped to 2.5GB of free memory. CPU usage was back to 1%. It looked as everything restarted by itself or maybe Directadmin did it . The websites were working fine and so was everything else. SSH, Pings, Control-Panel, Websites. Everything was working . I really just don't know how it happened. Out of a jammed state, system was back by itself. Apache processes were reduced too.
On Logging in, I just went to check the logs,
The previous log of apache was renamed and the new log of this date was itself created . I will just mention part of errors I see in the log,
Code:

If you see the last line, you may know why everything started working by itself . Apache actually restarted .
About the SH: Host command not found. I just ran this command on my server :
Code:
apt-get install bind9-host
It installed perfectly.
In directadmin logs this is what I found:

Time is round-about the same when the issue happened.

I just posted the logs which looked suspicious to me. Rest were all fine.
Changes made by me to Default DA Install :
The only change I had made to Directadmin was install add Lib-ssh2 module for Ion-cube loader and Zend extension to run it. These were basically just files needed to run from the Zend Extension. The file that was changed was only PHP.ini to enable Zend but I have restored the original one back so everything is default back again now because I want any possible cause to be minimized. But even on putting everything to default, the problem has not been fixed. This certainly means that the Default Directadmin install needs some changes.
Once again. Thanks for reading. If anyone thinks he knows whats the cause and whats the fix, please reply.
My Personal belief and experience :
I would talk about my experience and what I think could be the cause. I don't actually know how to fix but I can explain the cause based on my experience. I would base it up on the Apache Status:
Whenever this error occurs, I have observed in Apache status the number of requests are more than about 180 . When this request number of my website is crossed, the number of httpd processes start increasing by itself due to which RAM/CPU increase and the system becomes unstable and websites become inaccessible. Sometimes even if I have 100 visitors accessing, the request number stays under 30. But sometimes it randomly climbs up by itself.
Usually the requests number stays around 10-30 . There is a software of URL harvesting. If I run that software, the request number climbs to 200 and websites stop working. I believe this is a Bug in Directadmin. When a certain number of requests are made to the website, request number increases and due to each request number I believe the httpd process is assigned causing instability. Maybe on each 10 requests, a new httpd pid starts.
This is not certainly the software which does this Request number climb. Sometimes even without the software the request number climbs although the traffic is low at that time and hence causing this issue.
The URL-harvesting software is the only thing which can detect this error in my case because I don't know any other method to increase the number of requests.
Anyone who uses Directadmin ? Please give me their website address and also the server-status address so I can try harvesting their URL's and then we can see if this Error is my system specific or a Directadmin bug.
It could also be possible that the Software which I use is considered an attack . Maybe, default directadmin has no security for websites so we should secure it using some mods like to protect number of connections per IP . DA support asked me to install "limitipconn" module for blocking number of requests per IP, but in knowledge base I see something as "Loris-attack-module" to protect. But this would not fix the thing when the number of requests are increased by Multiple IP's ( i.e. not my software ) . I don't really know please suggest. So please advice if using one of these mods would be useful and which one.

Same log entries here
I have the same DA log entries, but i did not detect any strange system behavior.
the accesses come in clusters, about every 140 minutes.
Because of the timing, i do not believe this is driven by DA, but from an external automated source.
it is unfortunate that the DA error log does not give a better explanation of why DA would want to read from this ip address.

Actually, there was some strange behavior, but i had attributed it to something else entirely.
sh: /usr/sbin/sendmail: No such file or directory
and a lot of other system files are missing now.
i do not know if these things are related or not.

I asked DA about this issue.
They said that this Log file can be ignored. It is just a bad request because Google Chrome is not fully compatible with apache . It does send bad request sometimes. |
