At this moment swapinfo return this: Device 1K-blocks Used Avail Capacity /dev/ada0p3 944128 9060 935068 1% I don't think it's a swap problem, it appears to be memory leakage, but I'm unsure. This is one of two slave DNS servers, they only store the zones from the authoritative server and act as a recursive server for the internal users to the outside world. The number of clients is something between 700-1500 simultaneous users. Since we have a /21 internal space and a /23 public IPv4 space and there's no queries from the outside world, the port 53 is even blocked on the firewall to those machines. -- You are receiving this mail because: You are the assignee for the bug.
