I'm running a Django application. Had it under Apache + mod_python before, and it was all OK. Switched to Lighttpd + FastCGI. Now I randomly get the following exception (neither the place nor the time where it appears seem to be predictable). Since it's random, and it appears only after switching to FastCGI, I assume it has something to do with some settings.
Found a few results when googleing, but they seem to be related to setting maxrequests=1. However, I use the default, which is 0.
Any ideas where to look for?
PS. I'm using PostgreSQL. Might be related to that as well, since the exception appears when making a database query.
