[SOLVED] Install community builder fails on memory error

I've tried the lasted relaese to install on hjoomla 3 most recent.
It ends with a memory failure.
I tried 2.1.3 and previous release 2.1.2.
I tried it on a xampp installation on a windows 7 machine, with php7
I tried it on a debian nginx installation also php7.
Everything is up-to-date in both systems.
In php.ini 256M is set in both systems.
When I do a memcheck of php info, this is reported.

I made a little change to the php script (phpmemtest.php) that tests memory. Up to 270M (attached, remove .txt extension)
This is the result:
....
You have allocated 249M (261450600) memory in this php script
You have allocated 250M (262499176) memory in this php script
You have allocated 251M (263547752) memory in this php script
You have allocated 252M (264596328) memory in this php script
You have allocated 253M (265644904) memory in this php script

So the message that suggests that 128M is exceeded is wrong. This is not set. It is btw a very high memory usage that indicates there is something wrong. It must be a bug in the install files.

I found more about this on a German site. Same problem, same release.

You likely have something installed causing it to get stuck in an infinite loop. Disable 3rd party extensions in Extensions > Manage until it goes away. Aside from that I've no idea and am unable to confirm any problems with installation.

Install on a fresh Joomla 3 install goes correct. So I disabled all 3th party plugins and checked that in boths installs the same plugings are active.
To my supprise the CB plugin refuses to install with a memory fault (128MB while limit is set to 256!). Even that message is wrong. I'm starting to believe that there is more wrong. I will try to import the existing database on a new joomla install to see what happens then.

3 components of CB seem installed: builder Library, Builder system plugin and builder. The rest is also missing.

The cause seems to be the JCE text editor, most recent release 2.6.19. It is quite recent (weeks), but downloading this editor gives a 404 error. There where also 2 Dutch language modules with Tiny MCE that I removed and an old Code Highlighter that is no longer part of Joomla, also removed in the original web installation.

After importing the web database in a fresh local install with the required modules/plugings installed, installing the Community Builder went without errors.

I'm not exactly sure about the cause of memory failures, but JCE is most likely the cause of memory leaks.

Thanks for your hint! Problem solved.
