I don't understand but I really want secure relays. All my relays are on VPSs running Debian 6/7 64 and I only know enough Linux to get Tor going. Is being updated enough?
On Linux, that should be sufficient – looking at https://bugzilla.redhat.com/show_bug.cgi?id=186057, it seems that the last related issue on linux was fixed back in 2006.
I scanned a good portion of all the tor exit nodes now, this is the distribution of operating systems for the suspicious-looking relays:
1 Linux 1 Windows 98 1 Windows Server 2003 Service Pack 2 [server] 1 Windows XP Service Pack 3 [workstation] 2 Windows 8 [server] 2 Windows Server 2003 3 FreeBSD amd64 3 Windows 7 Service Pack 1 [workstation] 5 Windows 8 5 Windows Vista [server] 14 Windows Server 2003 [server] 17 Windows Vista 33 Windows 7 [server] 37 FreeBSD 50 Windows XP 206 Windows 7
So, looks as if Windows and FreeBSD are the problems.
