Description

I have a CF with composite column sort:

ColumnFamily: MyCF
  Key Validation Class: org.apache.cassandra.db.marshal.UTF8Type
  Default column value validator: org.apache.cassandra.db.marshal.UTF8Type
  Columns sorted by: org.apache.cassandra.db.marshal.CompositeType(org.apache.cassandra.db.marshal.AsciiType,org.apache.cassandra.db.marshal.IntegerType)
  Row cache size / save period in seconds / keys to save : 0.0/0/all
  Row Cache Provider: org.apache.cassandra.cache.SerializingCacheProvider
  Key cache size / save period in seconds: 200000.0/14400

  Compression Options:
    chunk_length_kb: 64

I'm using phpcassa to communicate with my Cassandra cluster.

I'm getting the following exception from time to time while reading/writing to this CF:

exception 'cassandra_InvalidRequestException' with message
'Invalid bytes remaining after an end-of-component at component1' in /phpcassa/thrift/packages/cassandra/Cassandra.php:256\nStack trace:
#0 /phpcassa/thrift/packages/cassandra/Cassandra.php(256): thrift_protocol_read_binary(Object(TBinaryProtocolAccelerated), 'cassandra_Cassa...', false)
#1 /phpcassa/thrift/packages/cassandra/Cassandra.php(229): CassandraClient->recv_get_slice()
#2 [internal function]: CassandraClient->get_slice('6034-28141406', Object(cassandra_ColumnParent), Object(cassandra_SlicePredicate), 2)
...

I've thoroughly checked my code, I'm always sending the same parameters to Cassandra, and there's no format error. My column name request is always AsciiType:IntegerType.

The weird part is that this is completely random. If I run a get() query once, I get the exception, but the following request with the same parameters succeeds.
