Hi Nick,
I can confirm that Rotter stops recording after the jack server receives

three or more xruns.  The program seems to be running, as does the jack

server, but all files are instead about 1k in size and have no audio.  Any

ideas?  Thanks!

you should use:
 =A0 ps aux | grep jackd
to establish whether jack has "crashed".
my guess is that had not crashed, but was no longer accepting new

clients and was otherwise hosed.
