Memory limit on shared hosting
Hello.
I have read topic where memory limit was discussing. I didn't attach importance to that. I want to ask you about your experience with memory limit on shared hosting package.
Thanks.

Well its more than about memory limit. Most hosts really watch for the CPU usage, because thats the biggest disturbance for other customers.

As I have heard there are some programs installed on the server for counting CPU usage.

A lot of hosts simply use the cpu/memory status in WHM (if they are a cpanel host), though there are a number of 'scoreboard' like softwares that can be put in place. The only one I know off the top of my head is a perl module called Apache:coreboard. Most of these target a specific type of memory usage (mysql, http, etc). Shell access an also have memory limitations so running things like fcgi processes can conflict there.

Most hosts I know invoke phpSuExec/SuExec which shows the processor and memory utilization of a specific username, and go by that. But, as previously explained, the numbers aren't always correct, and can cause unnecessary head-aches if the host doesn't know _exactly_ what he or she are looking at

The most accurate system out there is standard unix process accounting. The problem is, it is done on a per user basis, so it generaly doesn't include the apache user time in its totals.
In general, Most hosts use instantanious data more than they use any actual time based recording. So they will often give the boot to whoever is killing the server at the time that there is a problem, as opposed to watching cpu/mem use over time.Rock solid hosting and dedicated servers since 1998!

I should have explained myself better, karl. I've seen some hosts go bananas because they monitor top, which shows a PHP process using 68% CPU at the moment. Like vantage says, you need to go over a greater period of time
