Increasing the default PermGen size
L.S.,
Today, I ran into two occasions where the default PermGen memory
configuration was insufficient, first while installing the new
camel-drools demo that was created today and secondly when installing
a moderately large web project for testing purposes.
Would it make sense to increase the PermGen size to 128 MB out of the
box? I can imagine if I bump into this a few times in a row, some of
our users are bound to see the same thing happening too.
Regards,
Gert Vanthienen

I don't see any problem to increase PermGen by default.
+1

On my side, I'm creating the Jira in Karaf (we can link to the
SserviceMix one).
And agree with Karaf scripts.

Re: Increasing the default PermGen size
Posted by Gert Vanthienen <ge...@gmail.com>.
L.S.,
256 MB sounds like a fair value to me as well. Once it's added to
Karaf, we probably won't have to do anything in ServiceMix once we can
pick up a new version, so that sounds even better ;) I'll raise the
JIRA for ServiceMix 5 anyway so we can at least keep track of it.
Also, good to hear about the new Metaspace memory for Java 8. I do
wonder how this will affect production systems: most people will
probably want to leave the default setting to "unbounded", but I can
imagine some users will want to limit the amount of metaspace that can
be used so we might have to do the opposite for Java 8 and provide a
new environment variable in the Karaf scripts to limit this again.

I'm fine with it, though starting with Java 7 the PermSpace is removed from
the JVM (due to merge of JRockit and HotSpot implementation) So I'm not
sure how long this "issue" will still be present :)
Also take a look at [1]

On Karaf, we noticed an increase of the Perm when using a lot of bundles
refresh.
Agree with Freeman, it makes sense to increase in Karaf as well.
Maybe 256m is a fair value. WDYT ?

Hi
Isn't even 128MB a low value today?
Shouldn't we raise it to a higher value?
