In shell #1:
/etc/init.d/lircd stop
lircd -n -d /dev/lirc0

This might be enough to reveal what's up.

In shell #2:
irsend SEND_ONCE foo bar

This should definitely trigger some lircd spew if the initial command didn't.

I suspect you have an error in the way you merged the additional remote's config into /etc/lirc/lircd.conf, and lircd is barfing on it, but not enough such that its actually exiting...
