Code:

root@xxx [/usr/local/lsws-4.1RC2]# ps -ef | grep lscgid
root      4499 20214  0 02:43 pts/0    00:00:00 grep lscgid
root     27094 27090  0 02:28 ?        00:00:00 httpd (lscgid)

Thank you, George.
But then... which one I should strace?

27094 is it.

You have to produce the problem while stracing it.

too many processes running as "nobody", you need to increase "Process Soft Limit", "Process Hard Limit" accordingly.

DraCoola · #17 11-19-2009, 12:16 PM

Thank you for your suggestion. I will do that

By the way... how to make lsws showing for php process (path, file) just like php with apache did?

It cannot show that now, we need to update the LSAPI code to do that.

DraCoola · #19 11-19-2009, 01:02 PM

What a pity...

But I hope it has already placed on your to do list

I will hopefuly wait for that LSAPI update release.
Because, sometimes, many users (especially their addon domains and subdomains) are squeezing CPU more harder than their main domain.
So the server administrator could handle (trace) that CPU-squeezer-php-files more quick and exactly right on the target.

mistwang · #20 11-24-2009, 08:20 AM

You can try the php-lsapi 5.0b2, it will show the script name being executed.
You need to build PHP manually.
