(I assume by "persistent" you mean "long lived" not "stored on disk".)

No, this should not be a problem; AMQP connections are supposed to be 
able to stick around.

The number of simultaneous connections is limited by the number of file 
descriptors available - controlled by ulimit on Unix and the environment 
variable ERL_MAX_PORTS on Windows. So for lots of connections you may 
need to tweak this.

The mgmt plugin will let you know how many file descriptors are in use.

Cheers, Simon
