Memory Limit (67108864)

[Islam Mohamed]

I have a problem when it comes to the ActiveMQ. I need to know where exactly
I can re-configure the Active MQ to avoid the following error.

Note that I am using the ActiveMQ ver 5.5 on Ubuntu 11.10

Usage Manager Memory Limit (67108864) reached on queue://1000010. Producers
will be throttled to the rate at which messages are removed from this
destination to prevent flooding it.

And her is my configurations
