Web Hosting Talk : Web Hosting Main Forums : Hosting Security and Technology : What cause the server crash ?

[gmsi]

hi, i need some information
i have client that have a simple flash site averange visitor only 200-250 daily.
have enough space and traffic bandwith.
everything was working fine for a year

however last week suddenly receive 1200 visitors that day ( according to webalizer )

my reseller provider told me that one of my site crashing their server.
everytime they turn this particular domain, it crash other domain on that server.
so they have to shut it down. they suggest move the site to dedicated server.

my questions are
1. is this common issue? i know i was only a reseller so they must have other resller on the same server.

2. what other factors that one site/domain can crash a server. in my opinion when you look at the statistic above it should not be an issue.

3. is it because of many requests/visitor at specific time, my provider told me that this site use 99% of the server capacity.

4. will dedicated server solve this issue

i appreciate if you can share your experience or understanding about this technical stuff.


thanks
gmas

its depend of the site complexity,
if you run a web forum like these here, too many connecs can use too much memory, and if the reseller server inst good they can problaly crash the server!
if you run a VPS, in a good comp, it ll possible to to that easily

we see sites which run forum that has heavy traffic crashes the server performance where the loads jumps up to 40 and some times 60% of the CPU load. As forums relies on MYSQL, this might have been the cause of problems

[nick125]

It could be various problems, the httpd could be running out of file descriptors and segfaulting, mysql could be getting slamed if you site uses it, etc. There are a ton of reasons that a heavy usage site could "crash" a server. And, yes, a VPS or dedicated server would probably fix your problem. With a VPS or dedicated, if you drive your CPU usage to 100%, no one except for you will care, since no one else would be hosted on that server.

i guess,

you have flash website and it must be eating up lots of bandwidth of server, and the hosting company just disabled your account because your account might be getting more bandwidth then any other accunnts on the same server.

now in such condition, when hosting companies do not have any answer, they simpley use a common execuse that your account is crashing our server. because many other clients might hve small websites and small usage, company tries to balance all and chooses least hardware and network connection required. and in such condition when your account expects high usage, they disable it.

There should be a valid genuine reason to disable acount "just crashing" is too common.

I can't see how crashing the server isn't an answer... It is a big problem if one of the websites is using all the memory and in turn brings down MySQL and apache, then they reboot and it happens again... what else can they do? Find the source of the problem and disable it... But yes, their hardware may not be substantial but you cannot make that call because we don't know the host.

In answer to the first post:
If you have a sudden spike of traffic and there isn't enough httpd processes to catch it, it uses quite a lot of load to get more loaded quickly, this can cause the server to slow right down and maybe crash. It is the result of a server that needs to be optimized for that site.
