... I'm using Postgresql (makes no different whether it's 7.0 or the 7.1RC1) with ZPoPyDA and/or psycopg - they both suffer from the problem. What happens is that the child threads of ZServer die, leaving me with the top-level process (doing a waitpid on it's child) and the child (doing a select on the PCGI socket) Usually, they say something (--> log file, enabled with "STUPID_LOG_FILE=....") when they die. This may give you a hint.

Often they produce a "core" file, when they die. However, some configuration experts disable the core generation. Reenable them and see whether you get one. Then you can look into them with a debugger. Dieter
