Hi all, # unbound -h (...) Version 1.4.5 linked libs: event 1.4.14b-stable, ldns 1.6.5, OpenSSL 0.9.8g 19 Oct 2007 linked modules: validator iterator BSD licensed, see LICENSE in source package for details. Report bugs to unbound-bugs at nlnetlabs.nl I activated prefetch and prefetch-key today and I got high cpu usage on the unbound process. Since deactivating prefetch-key, I don't seem to have the problem anymore. There have been no higher q/s rates, so I am guessing this is no flood attack. Anybody experiencing similar?
