[rabbitmq-discuss] Memory leak with file_io_server,server_loop?

Mon Nov 5 23:38:52 GMT 2012

Not sure if we've found another memory leak or not.  We're running
2.8.6 and experiencing periods where we're triggering the
vm_memory_highwater_mark.  I've had to restart rabbitmq twice today
because of this.

I've attempted to force a gc, but it doesn't seem to affect the memory
usage appreciably.
