Really not. I just copy-paste my config in my post. As you can see, timeout value is defined. And even more strange here. Until my experiments error went away when I comment out part of "rules" section (some includes, but I'm sure that includes have a correct syntax), and return again after some changes in configs. I didn't found relations. Look like some incorrect code in localconfig.c (IMHO), but need a deep debug, for which I haven't time enough, unfortunately :( May be later.
