--------------------------------------
BTW, I don't understand how it can be a race, since the process is serial,
single thread.
> Randomly getting "Invalid bytes remaining after an end-of-component at

> I'm using [phpcassa|https://github.com/thobbs/phpcassa] to communicate with
> my Cassandra cluster.
> I'm getting the following exception from time to time while reading/writing
> to this CF:
> {noformat}
> 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',

> {noformat}
> 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.
