[SOLVED] Apache stats. NaN only on waiting threads

[nakom]

Hi forum, does anyone know what I'm doing wrong here?
as you can see from the picture the value of the waiting threads is NaN, all the other ones work fine.
if I run this command:
sudo -u cactiuser php /var/www/html/scripts/ss_apache_stats.php prod-web1 threads
thread_W:29 threadS:0 threadR:0 threadW:1 threadK:5 threadD:0 threadC:1 threadL:0 threadG:0 threadI:0 thread_O:964
it shows the correct value
step is set to 60 and heartbeat to 120
