I'm trying to use the compress spooler codec on a previously-working RMQ output, but encoding is failing with `Error encoding event {:exception=># ... `. I've stripped my config down to basic input/output and can reproduce it with the following: > input { > generator { > count =\> 10 > message =\> "test" > } > } > output { > rabbitmq { > codec =\> compress\_spooler { > spool\_size =\> 10 > } > exchange =\> "from-ingress" > exchange\_type =\> "direct" > host =\> "dev-queue1" > key =\> "filter-routing-key" > ssl =\> "true" > port =\> "5671" > user =\> "logstash\_user" > password =\> "[not\_telling]" > durable =\> "true" > persistent =\> "true" > } > } It seems to be an interaction between rabbitmq and compress\_spooler, as other outputs I've tried (file, stdout, tcp) don't throw this error. Can anyone else reproduce this and maybe shed some light on the cause? ---

What version of LS and the plugin are you using? What OS (and version)? What Java version and release? ---

Hey @warkolm Not sure why I didn't include versions 😕 Ubuntu 14.04.3 LS 2.0.0-1 logstash-output-rabbitmq 3.0.5 logstash-codec-compress\_spooler 2.0.2 Openjdk 7u79-2.5.6-0ubuntu1.14.04.1 ---

I think this would be worth raising as an issue here - [https://github.com/logstash-plugins/logstash-output-rabbitmq/issues](https://github.com/logstash-plugins/logstash-output-rabbitmq/issues) ---

@ceekay - any updates? are u still having same issue? I am reproducing the same behavior when logstash is communicating to Rabbitmq using compress\_spooler... it works without compress\_spooler but I don't want to submit uncompressed packages that contain only one line to Rabbitmq... did you find any alternative? ---

@oriol we ended up dropping compress\_spooler and writing our own codec with similar functionality. This also needs a slightly tweaked RabbitMQ plugin to ensure there's no message loss on shutdown, and we're still waiting on PR acceptance for that so we can't really release what we have until that happens. I'll update this thread when there's some movement there. ---

still no updates on this issue? I'm having the same problem with RabbitMQ 3.6.6, Logstash 2.4.1 and logstash-codec-compress\_spooler 2.0.4 ---
