I just found this beaker_expire_distros process in my devel environment, it has been dead for four weeks:
# ps -lf 30059
F S UID PID PPID C PRI NI ADDR SZ WCHAN STIME TTY TIME CMD
0 S root 30059 30057 0 80 0 - 23129 sk_wai Sep13 ? 0:00 /usr/bin/python /usr/bin/beaker-expire-distros
Looks like it got stuck talking to a Fedora FTP mirror:
# lsof -p30059
COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME
beaker-ex 30059 root 4u IPv4 8294590 0t0 TCP dhcp-40-138.bne.redhat.com:41668->ftp.cc.swin.edu.au:ftp (ESTABLISHED)
A reasonable timeout (perhaps 20 seconds) should be enforced for connects and reads for HTTP and FTP. Can't do much about NFS over autofs unfortunately.

Beaker 0.12 has been released.
