[Zope] APACHE TIMEOUT

Friends of Zope, I am a newbie who is learning Zope! Recently I have started getting timeout errors running Zope with Apache. I'm sure the problem is correctable but I am not sure where to look for the problem. I can connect and query Zope once and then I am locked. If I run Xserver at the server everything appears ok. Any Ideas?? RedHat Linux 6.0 Apache Zope (most stable version)
