Hello All, I have used Quixote and SQLITE/SQLSERVER for the last one year or so and found it perfect for an inventory management system in my company. I moved to my data to ZODB and found that although I can access the ZODB database from the python prompt when I launch my webserver (Twisted) the first hit gives me a locked database error. On tracing the calls I found that there were two seperate threads (or processes?) from Quixote trying to acess the database at the same time. Is there some way to avoid this two threads (or processes) problem? I think that the problem only comes up when using Quixote as I can acess the database programtically through Python.
