I installed a new clean "Perfect server" based on Debian Jessie in a openvz vps on my own local home server. After that went well i installed multiple php versions Latest php 5.3, 5.4, 5.5 fpm and cgi. Wen i test those 3 cgi versions they all three work right away in few seconds after i change te version te test page with phpinfo(); show the correct version. But wen i want to change the fpm versions this doesn't change the verion. I have to restart the vps to make the version change work. Is this normal behavior or is something wrong?
