thank you very much for running an analysis Bruno. i appreciate the
time you have put into it
i redeploy the apps but always have to restart the server afterwards as
some apps get jammed. i was considering deploying using
tomee-maven-plugin if possible to start new instance directly from
I see 20 org.apache.bval.cdi.BValExtension instances.
This seems consistent with the apps you are deploying in there. Do you
do redeploys of running apps?
Most of the usage is in cached objects:
Class Name | Objects | Shallow Heap |
Retained Heap | Percentage
11 datasources and 21 webapps. i have been considering merging
everything into around 5 webapps. it was useful to split it up at one
point of the development but now it seems unnecessary. does having lots
of webapps have a bad effect on performance?

is there a way to clear sensitive data out of a heap dump?

Yes, will delete afterwards.
Visual VM in useless with this, Eclipse Memory Analyzer works and it
seems a lot faster.
There is definitely an issue around "org.apache.bval.cdi.BValExtension"
and "org.apache.webbeans.container.BeanManagerImpl".
How many
yes please

i wondered if it was actually doing anything because activity monitor
wasn't showing visualvm using the processor or memory. so i checked the
log file and got this

thanks Bruno. i have started doing it this end as well as i didn't
realise it was important to compute the retained values. eclipse memory
analyser seems to have the retained values after loading but maybe
doesn't drill far enough in

Hi Matthew,
I've loaded the heap profile here but its taking hours to compute the
retained values. I'm tempted to cancel and try the Java 11 version to
see if it's faster...

i have got visualvm working now and it seems i already have a lot of
memory leaks with using @ViewScoped MyFaces managed beans.
uk.me.kissy.database.entities.jpa.extras.Testimonial looks like the
worst offender

It would be nice to take a look to that heap dump.

Are you including some bval dependency in the code of your own app?
You can zip that file. It will get much smaller. If you could share it,
it would be nice indeed.

Hi Matthew
It comes with the JDK, just type:

But that BValExtension usage is intriguing.
Can you please let us know the top 4 classes in the retained list?
This is on 7.0.5 plus with Oracle JDK 8?

i did wonder if 7.1.0 might have some improvements.

thanks Jean-Louis.
i used gdb to get a jvm.core on the live system as it is much faster.
then i used jmap to convert it to a jvm.hprof.
(https://www.atlassian.com/blog/archives/so-you-want-your-jvms-heap)
then i used eclipse memory analyser to get the dominator table, and
paths to GC root

I'd say probably before going too deep, I would just use the verbose:gc
option piped into a log file so it can be further analyzed.
It should show a memory increase to confirm.
Also when it gets slow, probably a jstack could also help to see where the
threads are.
As for the head dump, I also
Thant's interesting Matthew.
Usually I open those in jvisualvm. I go to classes and activate the
retained column.
That column will calculate the retained (effective) memory usage by class.
Usually it takes a while to calculate, that's why it's not on by default.

i had a recent memory leak which was stalling the server every couple of
days. so i did a heap dump and solved that problem.
then i decided to do another heap dump because the server is running
pretty slowly. each page is taking a few seconds to load on a 32GB
