already resolved, thanks for attaention.
as always the most mysterious issues are really trivial ones. This time
an error in configuration file.
It seems that CMAN reload command always seems to be performed without
errors - which is very annoying. In case of problems with rules one
should check if a number of rules and their list from runtime is equal
to those in config file - if not it may indicate that reload hits some
wrong syntax in the config file and parses it only partially, which
provides (as in our case) random results.
