Hello, We have setup nat server with src-nat event logging using ulogd2. After running for couple of day all of sudden the ulogd2 messages stopped. There was nothing related to connection events. When i run conntrack -L command and then conntrack -E command the logs starts appearing. Please help me out i did not find any clue why this is happening.
