It is Python 2.5.
Also, I should mention that the job in question uses cursors with a double
loop to get around the 1-minute query timeout. This used to fail around 1%
of the time with the backend termination error, but in the past 2-3 days
this has increased to 75% failure rate.
q = db.GqlQuery(queryStr)
cursor = None
while True:
q.with_cursor(cursor)
results = q.fetch(300)
if len(results) == 0:
break
cursor = q.cursor()
for p in results:
# Do something with each result
