Description jjasen 2016-10-28 18:18:21 UTC
Probably filed under pf:

I have firewall systems using pf, with ftp_proxy as well. Under certain circumstances, relayd will crash when updating a table if something else (such as ftp_proxy, tftp_proxy, or a local rules edit) has /dev/pf locked.

I've seen other cases, where an individual ftp_proxy will also fail, if something else grabbed /dev/pf as well -- and seeing "pfctl: DIOCADDRULE: Device busy " failures when doing manual updates is quite common.

relayd logs attached:
