Metaspace

[Mattias Ohlsson]

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.

This should be the expected behavior when no maximum limit is configured for MetaSpace explicitly.

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

• The JIRA Applications Memory Information screen Displays 0% Free MetaSpace

[Mattias Ohlsson]

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.

The other are not half "full"/red...

I think you need to explain what you mean by "metaspace", it's not a term I recognise when talking about Java memory settings.

see my screenshot in reply below.. cheers

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.
