[rabbitmq-discuss] server crashes with very fast consumers

[alex chen]

John,

I tried building my previous patched amqp_consumer with latest rabbitmq-c, 
however, the build breaks because the current amqp.h does not support 
AMQP_SIMPLE_RPC anymore.  Ideally amqp.h should support the following function, 
as commented in my patch:

/* amqp.h should support this */
int amqp_basic_qos(amqp_connection_state_t state,
                           amqp_channel_t channel,
                           uint32_t prefetch_size,
                           uint16_t prefetch_count,
                           amqp_boolean_t global)

It would be nice if rabbitmq-c maintainer could add this api.  otherwise, i have 
to take a look at the src code and see if it can be implemented.


thanks.

-alex

Alex,

I'm trying to reproduce your problems and I'm having a very hard time doing so.

Your example code is based on your own modifications to the sources in the 
rabbitmq-c/examples directory in some revision from last summer, which itself 
depends on some revision of rabbitmq-codegen from last summer. I'm having a hard 
time building it.

I'm guessing you've run all of this much more recently. Could you please mail us 
a bind.sh, producer.sh, and consumer.sh that work with the current 
rabbitmq-c/examples directory? Could you also add your modifications to the 
source code in the current rabbitmq-c/examples directory? This would help a 
great deal.

Even so, I've been able to reproduce some crashes, but I very much doubt they're 
the same crashes that you're seeing. Again, please tell me exactly what to do to 
reproduce your problem, starting with the current version of rabbitmq-c. Thank 
you.

Cheers,
John
