We are using it in production with no problems. I have noticed this issue (CARP + IPv4 aliases) with older (pre 9.x) versions of FreeBSD. I maintain some legacy 6.2 servers and had to eventually add ifconfig statements inside rc.local to get the links to coalesce. 6.2 appears to ignore _alias<n> directives entirely inside rc.conf, and has real issues if you add/delete aliases to a CARP interface while its up (both peers end up thinking they're MASTER). In 9.x it all works as expected at least for IPv4 (rc.conf carp<n>_alias<n> entries, aliases, on the fly reconfiguring). -- Adam Strohl http://www.ateamsystems.com/
