Hi, I have combination Apache, pcgi, Zope 2.5, gvibDA 0.9.7., Firebird 1.0.0 RC2 On pages using database, I often get 500 Internal Server Error and 50 Service Unavailable. I tested it with torture.pl and the results vary. Sometimes it's 100%OK, sometimes 75% errors. Pages without database use are allways OK. Do you have any idea, where can be the problem? Thanks Tomas.
