Timeouts but returned consistency level is invalid

[Michał Łowicki]

Hi,

We're using C* 2.1.2, django-cassandra-engine which in turn uses cqlengine.
LOCAL_QUROUM is set as default consistency level. From time to time we get
timeouts while talking to the database but what is strange returned
consistency level is not LOCAL_QUROUM:

code=1200 [Coordinator node timed out waiting for replica nodes'
responses] message="Operation timed out - received only 3 responses."
info={'received_responses': 3, 'required_responses': 4, 'consistency':
'ALL'}


code=1200 [Coordinator node timed out waiting for replica nodes'
responses] message="Operation timed out - received only 1 responses."
info={'received_responses': 1, 'required_responses': 2, 'consistency':
'LOCAL_QUORUM'}


code=1100 [Coordinator node timed out waiting for replica nodes'
responses] message="Operation timed out - received only 0 responses."
info={'received_responses': 0, 'required_responses': 1, 'consistency':
'ONE'}


Any idea why it might happen?
