I have the following handler that is called via cron. It is set to run
for 8mins...
def get(self):
logging.info("Deleting items...")
#set end time (8mins from now)
end = datetime.datetime.now() + datetime.timedelta(minutes=8)
now = datetime.datetime.now()
delete_fetch_size = 30
cursor = False
proceed = True
counter = 0
#start loop
while now < end:
#get items
if proceed:
query = Item.all(keys_only=True)
query.filter('status', 'FOR DELETION')
if cursor:
query.with_cursor(cursor)
try:
results = query.fetch(delete_fetch_size)
except:
logging.error('Failed to fetch.')
break
if results:
try:
db.delete(results)
proceed = True
cursor = False
if len(results) == delete_fetch_size:
cursor = query.cursor()
counter += len(results)
except:
logging.error('Failed to delete.')
proceed = False
else:
break
else:
try:
db.delete(results)
proceed = True
except:
logging.error('Failed to delete again.')
proceed = False
#no more results?
if not cursor:
logging.info('Deleted ' + str(counter) + ' Items')
break
now = datetime.datetime.now()
It spewed out the following error...

Any ideas what happened here? What does "Exceeded soft memory limit"
mean?
Thanks
