Meta space below always 0%.. should it be so?

Ah, my apologies, I've not had to deal with a client having memory issues with Java 8 yet, so I've not run into the term. If I understand it correctly, I'd say that's not a problem - it's supposed to dynamically re-allocate as it's required, so it should really be full all the time.

my question is about why metaspace always is full? I have a small usage of my JIRA instance, 3 GB server, and allocated JVM_MINIMUM_MEMORY 1024 m and JVM_MAXIMUM_MEMORY 1500 for jira.

We recognize the same situation, does it have any negative impact?

See previous comment.

Just upgraded from 6.4.2 to 6.4.11 In both versions, it is same situation as Mattias Ohlsson described (even after fresh start of machine and Jira 6.4.11). The Metaspace bar is always 100% used. @Nic Brough: the above screenshot shows 7 graphical bars, the 3rd from top is named "Metaspace" ... But we never encountered negative impact yet.

We have created the KB article below to clarify this behavior:
