When booting XEN system (both 4.6 and 4.3) with kernel (linux-image-4.3.0-1-amd64, pkg version 4.3.3-5) when started 6 to 7 small domU's, error messages are thrown:

xl toolstack is then rendered unusable (xl list, xl top, etc.) and hangs after xl invocatin.
Some of the started machines are still running in normal (accessible from network).

Earlier kernel on this system (3.14-2-amd64 #1 SMP Debian 3.14.15-2) works fine with both XEN 4.3 and 4.6
Have another system with 4.3.0-1-amd64 and XEN 4.6 what works fine, but there are only 1 domU.
