weird lsphp4 processes
 

Hi,
lsphp4 eats cpu too much,but server has quad core and can handle these processess heavily..
I have to find a solution quickly for this,

Note : almost all websites using php5.there are only 2 websites using php4.

You can limit the "Max connections" for the "lsphp4" external app.
also, you can try PHP suEXEC.
Check if lsphp4 has been built with all required modules.

A post from earlier this year from mistawang:

now max_connections is 5!
PHP_LSAPI_MAX_REQUESTS=100
PHP_LSAPI_CHILDREN=5

but nothing changed.php is already in suexec mode.why isn't happening this to php5?

note: php4 is build with standart extensions,zlib,mysql etc.as I said,there are only two customers using this.

All of your lsphp4 processes are running under user "apache", so suEXEC is not in use.
You can strace those lsphp4 processes to find out what are they doing.

you're right about suexec.but some php5 processess seems running vhost user rights.we migrate this server from centos/plesk 8.x to litespeed so How can I enable suexec mode both php4 and php5.there is no way to trace hosting users quickly

Is there a suEXEC option in Plesk?
LSWS need
"User/Group" or "suEXEC_User/group" in the <virtualhost ...> configuration from httpd.conf.

unfortunately plesk doesn't support things related security.They always works on beatiful themes,buttons,ajaxed admin menus..etc.:mad:
