Hello,
Yes, there is no need to restart. The fifo engine attempts to flush any
extra bogus characters whenever an error occurs, but it blocking
attempts to clear them until it encounters a carriage return.
Just push an extra carriage return to the fifo and that should clear out
the previous empty command and make it accept new MI requests again.
Regards,

Hello Brett,
A well formed MI command should end with two '\n\n' characters.
When you do
echo -e ":address_dump:my_fifo\n\n"
,your MI command ends with three '\n', because echo adds an extra
\n at the end, unless you use the -n parameter.
So what happens is that OpenSIPS successfully processes your
address_dump MI command, and then reads the third \n.
It treats it as an empty MI command, and attempts to block and
read the second \n signaling the end of the MI command, and there
it gets stuck.
Vlad,
Thanks for this explaination, that makes a *lot* of sense. However, I
feel like sending "crap" to the fifo shouldn't break it, right? At
least, it should eventually clear itself out or reset itself without
requiring a restart. Right? If I had sent it just one more carriage
return, do you think it would clear it out?
