[rabbitmq-discuss] RabbitMQ 2.0 broker crashes

Hi Matthew,

Thanks for the configuration details - is it possible to increase the file size limit?  Is there an upper limit?

I've just run my tests against a 2.2.0 broker running on an ubuntu server.  It works fine which provides further evidence supporting your hypothesis.

Would you like me to provide some test code reproducing the crash?

Yup, edit your rabbitmq.config file. You want to add a stanza including
{msg_store_file_size_limit, 16777216}. 16777216 is the default and is
16MB. You can reduce this as much as you'd like but if you make it too
small then you'll find performance starts to drop off. The minimum
rabbitmq.config file with this in is:

[{rabbit, [{msg_store_file_size_limit, 16777216}]}].

Note the trailing . is essential. According to
http://www.rabbitmq.com/install.html#configfile, under Windows, the
config file might be found in %APPDATA%\RabbitMQ\rabbitmq.config
