I'm filling my Django tables with data through a regular Python
program (not through the browser). After it runs for a few hours, I
get:
10557896: ERROR: gramps.py: line 121: Unhandled exception
Traceback (most recent call last):

MemoryError
The line that looks suspicious to me is the "self._result_cache =
list(self.iterator())". Does it look like that might be the problem?
I'm not manually doing anything other than adding data, changing data,
and calling .save() (eg, I'm not doing anything with transactions in
my code).
I looked at the chapter on cache from the book:
http://www.djangobook.com/en/beta/chapter14/
but I'm not sure how this is related. Although, if there was a Python
command to turn off caching while importing, that might be something
to try.
Any ideas appreciated,
-Doug
