I solved the problem and make some changes to php starter template and dmn-manager to generate the file when you create a new domain.
Put this code in your php5-fcgi-starter.tpl:
#!/bin/sh
# Kill all old process
ps ax -F | awk '{ if ( $3 == "1" && $1 == "{SUEXEC_USER}" && $12 == "/usr/bin/php5-cgi" ) { print "kill " $2 } }' | sh
PHPRC="{PHP_STARTER_DIR}/{DMN_NAME}/php5/"
export PHPRC
#PHP_FCGI_CHILDREN=10
#export PHP_FCGI_CHILDREN
#PHP_FCGI_MAX_REQUESTS=11000
#export PHP_FCGI_MAX_REQUESTS
and add this code in ispcp-dmn-mngr at line 2033:
$starter_tpl =~ s/{SUEXEC_USER}/$sys_user/gi;
Good luck to all!
For rats: sorry for bother you
