RAM drive disappears

Description

I use the Lucee/ Coldfusion RAM drive to quickly perform image manipulations like thumbnailing. Often I get the error [ram:///filename] doesn't exist. The whole RAM drive disappears. After a Lucee restart everything works fine again. It looks like this error randomly appears. So creating a test case is difficult. I have 65 GB RAM on my server. I use a lot of caching.This error is haunting me since Railo 4.

Environment

Linux, Apache, Lucee, Elasticsearch

I always have to restart the service.

Ram Resource cannot recover from this.

does that mean the only way to recover from this is to restart the service?

have found the reason for this issue. in case Lucee runs out of memory it starts to delete files from the ram cache, actually the JVM does it, because we are using soft references.
Problem is, this does not happen in a organized matter.
the JVM should start deleteting file on top of the tree, so no elements (directories) that have children.
in this case the root directory “/” is deleted and the Ram Resource cannot recover from this.

workaround, make sure not to use to many files in the ram cache.
