Hi Nicholas,
Thanks for your reply.
This was one of my concerns. Even running my loop only one time per hour.
So, to prove again that there is a strange behavior , I changed the loop to:
for x in range(startid, lastid):
r=memcache.get('%s' % x)
if r and r > 50 and not Foo.all().filter('id', x).fetch(1):
logging.error('there is no register for id %s' %x)
a=Foo(id=x)
a.put()
It's ok to assume that I will not have 50 requests (each request do a
memcache.incr()) in less than 3 minutes.
Doing this way, it seems even more, that there is something wrong. I'm not
sure if it is me that doing it wrong :-).
thatnks again.
