Error is:

SQLSTATE[HY000]: General error: 2014 Cannot execute queries while other unbuffered queries are active. Consider using PDOStatement::fetchAll(). Alternatively, if your code is only ever going to run against mysql, you may enable query buffering by setting the PDO::MYSQL_ATTR_USE_BUFFERED_QUERY attribute.

PHP 5.5.25
mysqlnd 5.0.11-dev - 20120503 - $Id: 15d5c781cfcad91193dceae1d2cdd127674ddb3e $
PDO (1.0.4dev)
pdo_mysql (1.0.2)
Symfony 1.4
Doctrine 1.2.4

I already tried with setting PDO::MYSQL_ATTR_USE_BUFFERED_QUERY but seems not working and still facing the error.

It seems to be having some issue with mysqlnd native library.

Apart I made sure that PDO library is using mysqlnd native library and not the other one:

php -r "var_dump(function_exists('mysqli_get_client_stats'));"

Please help.

Many thanks.

Thank you for this bug report. To properly diagnose the problem, we
need a short but complete example script to be able to reproduce
this bug ourselves. 

A proper reproducing script starts with <?php and ends with ?>,
is max. 10-20 lines long and does not require any external 
resources such as databases, etc. If the script requires a 
database to demonstrate the issue, please make sure it creates 
all necessary tables, stored procedures etc.

Please avoid embedding huge scripts into the report.
