I added options timeout:5 attempts:1 no-check-names and it doesn't solve problems.

Some programs like apache, postgresql, mysql doesn't have any problems with dns - it's great :) But some programs doesn't want to run without dns - sudo, samba, mc (and probably many, many other) - from my point of view this is a big problem.
