Alfresco Community 7.1 creating large volumes


I noticed a large disk space consumption in my alfresco instalation and during a investigation, i found some volumes  undeclared in my compose (green itens are expected, because it was declared on my compose).

Sample content of volume: 


If i do a command volume inspect, a can see it was crated by SOLR6 and ACTIVEMQ.

The problem it's creating new volumes, and keep old volumes without referece with the containres. Docker documentation  called it "pending volumes". 

I'm using the following docker command to remove this volumes, but its needs to be executed periodically.

docker volume ls  -f dangling=true --filter name='.*[^volume]$',   --filter name='.*[^letsencrypt]$'

docker volume prune $(--filter name='.*[^volume]$', --filter name='.*[^letsencrypt]$')

My questions is: 

-What is this files (some  type of solr backup and temp files of activemq) ? 

-Is there a way to prevent the creation of this volumes?  Or at least to remove aumaticly  old data "pending volumes" ?

What is the correct approaching to handle with this case. ?
