Hello everyone!
I'm experiencing trouble with jack and multiple servers. The moment I start
a second jackserver (for net I/O) and try:
jack_lsp -s new_name
jack_lsp segfaults.
If I start jack_netsource first (by accident or should it be that way?) and
then start jackd for net I/O, I get a segfault from the new jackd.

jackd -N new_name -dnet -r16000 -b8 -i1 -o1 -I0 -O0 -l 5222
creating net driver ... net_pcm|16000|1024|5222|1|1|transport_sync:1
bind error
netjack: period : up: 0 / dn: 0
netjack: framerate: 16000
netjack: audio : cap: 1 / pbk: 1)
netjack: midi : cap: 0 / pbk: 0)
netjack: buffsize : rx: 0)
[165384.703633] jackd[21189]: segfault at 8 ip b804f24b sp b6a572c0 error 4 in
Segmentation fault

If I start the jackd first and then type jack_lsp -s new_name
[165501.994692] jack_lsp[21200]: segfault at 0 ip 08049078 sp bfea7c50 error 4
n jack_lsp[8048000+2000]
Segmentation fault

I'm running jackd version 0.119.0 (from svn), a kernel with
lowlatency options chosen (no patches though) and if that is of any importance
ALSA version 1.0.20.
Can someone help here?
Kindly yours
