After Upgrade to 0.8.8b script_server.php no more working

[cbrassel2]

ok, so I have just migrated my cacti to new server and new cacti release.

Everything is working fine, only the graphs served by script_server.php are not working on most of the hosts.

So in the cacti log I have this :
10/01/2014 01:45:07 PM - CMDPHP: Poller[0] Host[803] DS[5500] SERVER: /usr/share/cacti/site/scripts/ss_host_disk.php ss_host_disk x.x.x.x 804 2:161:500:1:10:cms007:::::: get total 7, output: U

if I test the script server manually I get the correct data :
# php script_server.php
PHP Script Server has Started - Parent is cmd
/usr/share/cacti/site/scripts/ss_host_disk.php ss_host_disk x.x.x.x 804 2:161:500:1:10:cms007:::::: get total 7
50784489472

On some hosts it's working .. on some not .. i can not find any logic behind this ..

Has somebody any idea ?
