It's occurred on coordinator (not always primary or secondary of this uid-PK)
when I execute query (PHP or Python client got "TSocket read 0 bytes"
exception):
{code:sql}SELECT * FROM home_timeline WHERE uid = 0x52dcbc794989a6ea2c8b4569
ORDER BY tuuid DESC LIMIT 32{code}
If limit < 32, then its ok. When ORDER ... ASC its ok. When ConsistencyLevel 1
its ok.
On one node data is inconsistent with two others, and read repair won't work
(32-nd element is odd).
Our RF = 3
