Interface conversion panic while running clustered

[CVTJNII]

While testing in a cluster one of my nodes fell over with the following panic:

[query] 2015/09/25 22:53:40 SELECT mean(value) FROM "riemann"."default"."Test Data" WHERE host = 'Datagen 1' AND time > now() - 15m GROUP BY time(1s)
panic: interface conversion: interface {} is map[string]interface {}, not *influxql.meanMapOutput

Full panic is over 500 lines so I have pastebinned it here: http://paste.ubuntu.com/12603851/

As I'm currently testing the cluster was running in Docker. Unfortunately docker-compose shut the containers down when this happened so I don't know how the cluster would have recovered. I'm currently working on migrating my tests to Vagrant to avoid any docker issues.

I have not attempted to reproduce as I'm working on moving from Docker to Vagrant for testing. Please let me know if you need any further information, I will update if this re-occurs outside of Docker.

• Host OS: Ubuntu 14.04 running in Docker
• Install method: .deb from http://influxdb.s3.amazonaws.com/influxdb_0.9.4.1_amd64.deb
• Influx Version: version 0.9.4.1, branch 0.9.4, commit c4f85f8

This has been fixed in the 0.9.5 release. You can run with the fix by installing a nightly build.
