-------------------------------------
There are several memory leak fixes in the 3.1.x fixes branch, I'd recommend
giving that a try,
> Memory leak when adding connection.sendTimeout=3000 to a failover transport
> ---------------------------------------------------------------------------

> Key: AMQCPP-286
> URL: https://issues.apache.org/activemq/browse/AMQCPP-286
> Project: ActiveMQ C++ Client
> Issue Type: Bug
> Components: Transports
> Affects Versions: 3.1
> Environment: Ubuntu 9.10 with self-compiled ActiveMQ-CPP 3.1.0
> Reporter: Martin Carpella
> Assignee: Timothy Bish
>
> When adding a connection.sendTimeout to a failover transport, a memory leak
> will occur.
> In the sample program provided on the homepage, the following broker caused
> the problem:
> std::string brokerURI =
> "failover://(tcp://localhost:61616)?connection.sendTimeout=3000";
> Valgrind reports the following losses (only parts with "definitely lost"
> included):
> ==20454== 800 bytes in 100 blocks are definitely lost in loss record 26 of 39
> ==20454== at 0x4025390: operator new(unsigned int)
> (vg_replace_malloc.c:214)

> Using the URI
> std::string brokerURI = "failover://(tcp://localhost:61616)";
> doesn't produce any "definitly lost" or "indirectly lost" records.
