这种错误并非每次都出现。当应用程序运行多次时，我们已经看到了这个问题。有人能帮我吗？

sql_query = 'SELECT * FROM hourly_table where mac=? and name=? and processedhour >= ? and processedhour < ? ;'

Traceback (most recent call last):
  File "/opt/Extraction/main/CassandraOps.py", line 1229, in selectConcurrent
    select_statement = session.prepare(sql_query)
  File "cassandra/cluster.py", line 2496, in cassandra.cluster.Session.prepare (cassandra/cluster.c:43515)
    raise
