Can not start broker

[mindphuk]

Next problem is, that I get

ERROR: clCreateContext() -6

Here I found, that -6 means out of memory http://hashcat.net/forum/thread-2635.html
However my server now runs 16gb ram
root@debian-hc:~/oclHashcat-1.20# free -h
total used free shared buffers cached
Mem: 15G 108M 15G 0B 8.1M 27M
-/+ buffers/cache: 72M 15G
Swap: 4.1G 0B 4.1G

I just installed the broker node on a xen VM and gave it 15gb but it still crashes with -6
Version of hashcat that I am running is oclHashcat v1.20

oclExample0.sh stops with
