I do : ps -aux  . There is one zope process (user : zope) running in 
every moment :

zope     19004  0.3 11.0 171460 114380 ?     S    09:58   0:16 
/usr/bin/python2.3 /usr/lib/zope2.7/lib/python/Zope/Startup/run.py -C 
/var/lib/zope2.7/instance/ ...

However, there are a lot of apache process (6) running.

Do you know another way to obtain the number of zope threads running?
