[Zope] Calendar Crashes

I am a newbie and this is my first message to this list. I managed to install the latest version of the Calendar Product and got it working ok. A few hours later my Management interface disappeared and the ZSever died with an error message involving a file descriptor. I tried restarting several times. In the end I reinstalled the whole thing. Everything seems to be working ok. Is this usual? ===== Philip Swann, Les Grands Chenes, 10, ch.
