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?

This has all the memory contents.
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 apps and datasources do you have deployed?
Did you try to replicate this with one of the demo apps?
Cheers

it is just dawning on me how much sensitive information is in these
heap dumps. i probably should have asked before but will you keep it
private? i thought there was only object sizes and stuff but it is
all in there...

I see a lot of org.apache.bval.MetaBeanCache
that handles org.apache.bval.cdi.BValExtension
With EclipseMAT can show the retained heap.

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...

hi Bruno,
no i am not directly using BVal as far as i am aware
i zipped it to under 600MB. i shared you and Jean-Louis a link via
google drive. let me know if there are any problems

Hi Mathew,
Thanks.
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.
Cheers!

i can make the jvm.hprof available by gogole drive or similar (at

it is 3.2GB

Hi Matthew
It comes with the JDK, just type:
$ jvisualvm
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?

hi Bruno,
i can't find visualvm in centos. i had it in ubuntu but i
don't
know which centos repo it is in. i suppose i could download it
directly...
eclipse memory analyser gives me a retained heap size of
785,781,368 for org.apache.bval.cdi.BValExtension which is
50.38% of everything.

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.

TomEE 7.0.5 plus
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 system. (i did clear out work directory)
it turns out that more than half of the memory is consumed
with org.apache.bval.cdi.BValExtension. is this fairly
normal?
using Eclipse Memory Analyser i have dug into shortest routes
to GC root but i don't find any of my objects listed there.
mostly BVal stuff. are there any tips for debugging heap
dumps?
