View 7 Repliesi've noticed a number of times in the past few weeks where the spamd process gets stuck (apache 2 server / whm) with a single user name running the process. there is no spam being sent out, no major incoming influx of mail either - the process is just stuck but consumes 100% of cpu and runs for ages before it terminates itself.
for e.g. right now my top output:
2789 <username> 25 0 99 287:44.76 1.3 79760 49m 2288 R spamd child
the 287 is the cumulative CPU time - no way it should be stuck like this.
how i can figure out what's causing this problem?
How can i set user limit to access web site ,
Ex:- if my site access 10000 users at a time and then if any more user access that site it will receive error or custom error page.

Is there any apache module which can limit user download daily. e.g. userA can download XX GB per day.
I am using mod_cband but it seems it can't do something like that.
I run 10+ sites on my dedicated server.In last 7 days one of them used over 1.7 TB of bandwidth.
I can't suspend that domain because it's mine.
I can't ban the IP of those who use considerable amount of bandwidth because they are a lot.
So i think about software/mod/whatever else that limit bandwidth usage per user(IP) per day! is there any one who has experience about this situation?
I want to limit resources like CPU and RAM maybe as a per user setting on a Windows Server 2003.
I've read about Windows System Resource Manager but from what I see it applies to per-process.
Is there a solution (freeware maybe) for this?

My sites are going down frequently, I have to restart apache to get them back.I checked the cpu and memory usage logs on whm, and they are well with in limits.
But my hosting support fellow is saying other wise.

Our logs indicate that from time to time your VPS is going above the RAM Guarantee, this puts your services in danger of going offline until the RAM usage is back under the guarantee. If you continue to see these problems, we recommend either reducing the RAM usage by disabling any unused services, purchasing a guaranteed RAM upgrade, or upgrading to the next plan, to help alleviate the problem.
I've been with zone.net for a couple months now, and I have a guaranteed 512MB of memory, which I seem to constantly be hitting, which seems to result in processes being killed and http access vanishing. Growing quite annoying.
I'm looking into moving onto a new provider that can provide more guaranteed RAM for about the same price.
Space isn't a huge deal, I'd do fine with a meager 5GB. Bandwidth I need at least 200GB, but wouldn't mind more.
I'd like to stay managed if possible, as I'm not as well versed in server workings as I should be. Also am in need of cPanel, which I know is a spendy sucker.
My budget is something around $70 a month, and I don't really want to go much higher than that. Still a poor college boy :/
Can anyone suggest such a provider? I've browsed around a lot of the VPS hosts but can't seem to find one that has as much RAM as I need for a decent price. All the ones that seem to have 512MB+ are pretty expensive, and offer a lot more other stuff (space/bandwidth) than I need.
As a final note, the line speed isn't that big of a deal. I'm currently on a 3mbit and am surviving, but going back to a higher speed line would be great
I started tracking and collecting information about every page load on my site, which made the DB grow very fast. In 24 hours I had over 1.4 million INSERTs, so the DB will grow by over 170MB/day. The inserts so far didnt affect the performance of the server (dual clovertown, 4gb ram, SCSI HD), but at this rate the DB will grow by over 5GB per month. Is it a good idea to let the DB grow to those sizes? Would it affect performance if a table had several 10s of millions of rows? Public doesnt run any SELECT/UPDATE queries on that table, only admin does (me).

Code:
tar -cpvf backup-`date '+%d-%B-%Y'`.tar --exclude=/var/www/html/tempjunk /var/www/html
To make some backups. It works fine, but here's the problem: it really takes a toll on server load. Server load seems to go up at by around +3 or more. I'm wondering if there is a way to use less CPU usage on that command, or is there another command that uses less usage. I'm not concerned if it backs up slower by starving the amount of CPU usage it has, so if there's a way to do this any method?
