[Samba] smbd does not start NT_STATUS_NO_MEMORY

[Dr. Lars Hanke]

I'm trying to set up a simple test server, but smbd fails to start:

[2016/11/14 00:21:24,  0] ../source3/smbd/server.c:1241(main)
   smbd version 4.2.10-Debian started.

however, there seems to be enough memory left:

free -m
              total       used       free     shared    buffers cached
Mem:          7892       5241       2651         18 32       4109

Swap:        15255          0      15255

The configuration is simple:

# Global parameters
[global]
         unix charset = LOCALE
         workgroup = Workgroup
         server string = µAC-Samba %v on %h
         security = USER
         map to guest = Bad User
         idmap config * : backend = tdb


[test]
         comment = Test share
         path = /srv/test
         guest ok = Yes

Thanks for anything helpful,
