[rabbitmq-discuss] Windows RabbitMQ Crashes and Blue Screens under Load

We've let loose one of our testing ninjas on RabbitMQ for load testing, and
we're consistently running into issues when the high memory watermark is


Windows Server 2003 32-bit , Erlang R15B 32-bit, Rabbit 2.7.1


2,000 Consumers each with their own queue bound to a direct exchange

1 Producer, publishing a 2 MB message to the exchange, once every second,
for a total of 50 seconds


Everything behaves as expected, until the memory footprint hits the high
watermark, at which point:

On a physical machine: ERL process crashes and dump file is created

On a Virtual Machine: Blue Screen of Death is shown and server reboots


VM environment = VMware, Inc.R vCenter Lab Manager 4.0 (


One other note is that we see the same problem with ERL R14B04 and Rabbit


I have looked through the log file and also turned on the console debug
output, and nothing seems to be jumping out as an error.  If needed, I can
upload the minidump from the Blue Screen and the ERL crash dump file, just
point me where to do it.


Let me know if there is anything else I can do to try and help get this




In the rabbit log, there are no errors, and only a few warnings 20 seconds
before the crash:


=INFO REPORT==== 11-Jan-2012::10:55:53 ===

closing TCP connection <0.4405.0> from


=WARNING REPORT==== 11-Jan-2012::10:55:53 ===

exception on TCP connection <0.20552.0> from




In the console output log file for the physical machine, this is the only
message I see:


starting direct_client

starting notify cluster nodes


broker running

Eshell V5.9  (abort with ^G)

(rabbit at QEDLP082)1> 

Crash dump was written to: C:/Documents and
Settings/Administrator.QEDLP/Application Data/RabbitMQ/erl_crash.dump

eheap_alloc: Cannot allocate 6731340 bytes of memory (of type "heap").

in message_loop

win32sysinfo:Erlang has closed.
