[rabbitmq-discuss] Receiving errno 10054 (WSAECONNRESET) writing to queue

[Sigurd Høgsbro]

We have a small transcoder python app running on Windows XP (SP3)
within VirtualBox 3.1.2 (1 cpu) on Ubuntu Karmic. Python version
2.6.4. It uses amqplib v0.6.1 to speak with Rabbitmq (rabbitmq-
server_1.7.1-1_all.deb from rabbitmq debian repo).

The python app:
1. waits for WMA lossless files in messages sent on a queue, which it
saves to disk
2. runs a transcoding cmdline app to convert WMA to FLAC
3. sends back the FLAC file to the response-queue specified in the
incoming request
4. Acks the message incoming request

This worked fine on a few small test files, but when used in anger
sending the response in step #3 fails with:
[Errno 10054] An existing connection was forcibly closed by the remote
host

The AMQP server and sending app and transcoding instance within
VirtualBox runs on the same 4GB Core2Duo laptop, so there are no
obvious external network factors affecting this.

Any ideas?
