iOS archive-build stopped by jetsam on startup

[iOSDev]

Hello,

i built an qml application for ios devices using qt 5.4.
I am able to run debug and release builds using Xcode (6.3) on my test devices without any problems.

As soon as i create an archive (for upload to the appstore) the application doesnt work anymore.
My application gets killed right on startup by the systemtool "jetsam".

I get the same behavior for a "standard template application". So when i create a new "qml application project", build an archive without changing anything and install it on my device i get the same problem.

I couldn't find any posts/bug reports regardings this issue.
Do i miss something?
