thanks for that information. I forgot that issue because I had some reboots
in the last months so the memory exhausting did not occur.

But: yes, I run linux: SLES 11, SP3
# uname -a
Linux dnsbl 3.0.101-0.15-default #1 SMP Wed Jan 22 15:49:03 UTC 2014  
(5c01f4e) x86_64 x86_64 x86_64 GNU/Linux

Now I definitive know I have to restart NSD weekly...
