[rabbitmq-discuss] Intermittent failure connecting to RabbitMQ

Tue Nov 6 23:23:59 GMT 2012

I've got a RabbitMQ service running on a Windows VM and after the service
has been running for a while and successfully processing messages, the
following error occurs in our client (.net code)

06/11/2012 16:30:13.143 - [Error]: Error configuring RabbitMqQueueProvider,
None of the specified endpoints were reachable

Endpoints attempted:

------------------------------------------------

I've looked through the rabbit@*.log and rabbit@*sals.log and see a series
of connections closing.

What's causing this problem; no further connection is possible to the
RabbitMQ server after this? Any suggestions are appreciated. 

I was running the latest build of Erlang/RabbitMQ but downgraded this to an
earlier version to see if that corrected the problem but it didn't.

(Windows 2008 R2 Server with firewall turned off).

Logs relate to this version:

rabbitmq-server-2.7.1.exe

otp_win32_R15B.exe

Also tried with same result:

rabbitmq-server-2.8.7.exe

otp_win64_R15B02_with_MSVCR100_installer_fix.exe
