I'm still having some problems with this. I'm using six instances of Rotter, and patching them one per physical input with esjit. All seems to go well for a while, usually; even though xruns stack up the recording still happens. However, once in a while the files being written by Rotter get mangled, resulting in there being a file of size 800k or so rather than the circa 50 megabytes that is expected. I then have to kill the Rotter instances, and jackd, and start over. I've tried this on Ubuntu Studio 11.04 and the latest Arch, with an Edirol FA-101, on a P4 3ghz with a second sata drive as an audio volume. Most vexatious is that Rotter doesn't report any issues even with the --verbose flag, and neither does jackd (other than xruns of course). Roberto and Lieven mention integer overflow; is this something that can be dealt with, or is it a hardware limitation?

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.
