[uml-user] Running named in UML with a lots of zones

[Thomas P. <Pre...@in...>]

Hello folks,

I wanted to run named 8.3.3 in a UML (patchlevel 46) with a huge
amount of zones. The UML-box itself runs the actual Debian 3.0.

The box runs in SKAS mode properly, everything works fine.

I know, that starting up the same nameserver with the same zones
on a physical machine needs about 300MB for the named process, so i
was curious whats about uml with this.

The start of named is very time consuming, I think it took a few
hours. When it was start up in the morning, I saw the following
error again and again:

  map : /proc/mm map failed, errno = 12

This is the named process:

  USER       PID %CPU %MEM   VSZ  RSS TTY      STAT START   TIME COMMAND
  root       190 23.2 60.7 295716 292932 ?     R    Jan16 136:50 /usr/sbin/named

netstat -tulpen shows me no open port 53. The box is online, but
it is a little bit slower than I am used it normally would. 

The host itself has 512MB RAM physically installed with a swap of
256MB. The memory usage of the host is normal, i.e. normal amount of
allocation of physical and virtual mem. The host runs Debian 3.0,
too.


Greetz,
