I found the problem with ulogd not starting. Reading through the example config:

/usr/share/doc/ulogd/ulogd.conf

I noticed that the /etc/ulogd.conf file from the recent system upgrade is incorrect.
Here is the corrected ulogd.conf, which was missing the IFINDEX plugin in the stack:

[global]
logfile="/var/log/ulogd.log"
loglevel=5
rmem=131071
bufsize=150000

plugin="/usr/lib/ulogd/ulogd_inppkt_NFLOG.so"
plugin="/usr/lib/ulogd/ulogd_raw2packet_BASE.so"
plugin="/usr/lib/ulogd/ulogd_filter_IFINDEX.so"
plugin="/usr/lib/ulogd/ulogd_filter_IP2STR.so"
plugin="/usr/lib/ulogd/ulogd_filter_PRINTPKT.so"
plugin="/usr/lib/ulogd/ulogd_output_LOGEMU.so"

#stack=log1:NFLOG,base1:BASE,ip2str1:IP2STR,print1:PRINTPKT,emu1:LOGEMU
stack=log1:NFLOG,base1:BASE,ifi1:IFINDEX,ip2str1:IP2STR,print1:PRINTPKT,emu1:LOGEMU

[log1]
group=1

[emu1]
file=/var/log/ulogd.syslogemu
