The System is freezing, it's fast 10 seconds I guess, but it's freezing when scan run. . Also, the debug (routes or all) is disabled in our config.
About that you mencioned with relation the nontrivial additional memory, have some place that can I check or provide some usefully information from my system?

Unfortunately i don't have FreeBSD 11 here now to test it. Also it is 'system freeze' or just BIRD freeze? There are two possible issues - logging and memory: Enabling 'debug {routes}' or 'debug all' for Kernel protocol could slow down the scan significantly. Kernel table scan on BSD require a buffer for all routes, so it may require some nontrivial additional memory during routing table scans. -- Elen sila lumenn' omentielvo Ondrej 'Santiago' Zajicek (email: [email protected]) OpenPGP encrypted e-mails preferred (KeyID 0x11DEADC3, wwwkeys.pgp.net) "To err is human -- to blame it on a computer is even more so." --
