[linux-audio-user] jackd: too many servers already active

[Ken Schutte]

I used to have jack working fine on my system, but lately strange things 
have been happening.  Right now when I try:
   jackd -v -d alsa
I get,
   too many servers already active

I've also tried different variations on this (-R, etc), and using 
qjackctl.  I can't find any other jack processes ("ps aux | grep jack" 
shows nothing).  I get the same thing right after rebooting.  Alsa seems 
to be working (aplay, etc).  Can anyone give some advice?

thanks.
