Hi,

Recently, i have encountered a blocking issue.
I'm trying to upsert a document "10 times" in a sharded collection, this latter is indexed on two keys (date and key).
In addition if i execute the same operation in mongo shell it succeed
I use pymongo driver.
the following code explains my operations:

for i in xrange(10): # @UnusedVariable
collection.update(

,

, upsert=True)
if self.kpi_data_exist(None, data["key"], data["date"]):
break
gevent.sleep(0.2)
else:
raise Exception("Insertion fail of:"+str(data))
