pflogd on x86_64

Hi,

Does anybody has a working pflogd on x86_64? Or is it only me?

Symptoms:
  - /var/log/pflog created, but empty.

  - pflogd stuck in initialisation:
         # ps ax | grep pflogd
         11923 ??  SLMs     0:00.01 pflogd: [priv] (pflogd)
         11924 ??  SLM      0:00.00 pflogd: [initializing] (pflogd)
         11937  1  SLM+     0:00.00 grep pflogd

  - suspect debug messages:
         # pflogd -D
         [priv]: msg PRIV_OPEN_LOG received
         pflogd: send_fd: sendmsg(4): Invalid argument
         pflogd: send_fd: sendmsg: expected sent 1 got -1

The privileged pflogd seems unable to send its /var/log/pflog file 
descriptor
to its children process, which is waiting.

Maybe it's not a x86_64 thing, I haven't tried on a 32 bits platform.

Regards,

Fanch
