>Description:
With the addition of one or several tables ~1500-2000 or more values in the short term, about 1 minute, the rules begin with the tables do not behave properly, ie then when the work should not, then the other way around - do not work when the need.
At the same time the problem with the flush of tables, similar to the PR "kern/127209" (http://www.freebsd.org/cgi/query-pr.cgi?pr=kern/127209).
>How-To-Repeat:
