[rabbitmq-discuss] RabbitMQ crash without errors

[Fernando Morgenstern]

Hi,

I have a RabbitMQ server which had been running for 2 months without
any problem. It handles 3 queues ( set as durable ) and a very low
message rate ( ~60/day ).

Last night it simply crashed and *lost all messages in queue*. It
seems to have stopped working around 4 am and only came back at 8 am
after a manual restart.

I tried to do a grep in /var/log/rabbitmq for ERROR but the only
messages that i found were these ones:

./rabbit at mr.log:=ERROR REPORT==== 14-May-2012::20:02:31 ===
./rabbit at mr.log-exception on TCP connection <0.26131.1469> from
127.0.0.1:62497
./rabbit at mr.log-{bad_header,<<"GET /api">>}

Which looks like a problem in client and shouldn't crash server.

My questions are:

1) How should i proceed to investigate this problem? Are there other
logs that i should look?

2) Why RabbitMQ lost all messages if all queues were set as durable?

RabbitMQ/Erlang version 2.7.1 / R14B04
OS: CentOS 6.0
