Not sure if this will help, but here's how I'm managing it.
I'm running Ubuntu Server 11.10 with darkice from the Ubuntu repositories and a (LAN) local icecast server.
We use a process monitor, god (http://godrb.com/), which keeps an eye on things - jack, rotter and darkice make up each encoder node we run. We run a couple with redundancy configured in icecast to guard against catastrophic software problems or hardware failures. Nagios monitors for process state to ensure god's doing its thing.
https://gist.github.com/1915661 is the darkice.cfg and our audio.god file (which tells god how to run jackd, rotter and darkice).
If darkice crashes it's picked up automatically by god, but this hasn't happened with us - darkice's failure mode on one box (gentoo) was to encode, but with large quantities of static, after a few weeks. We don't get this on Ubuntu, though.
Our icecast2 config is standard, with the exception of the source and relay passwords, and the mount points (but that's just to configure fallback sources), plus some aliases.

Hi Tim, I'm pretty sure this wasn't directed at me but hopefully I can hijack some hints. I'm running Ubuntu 10.04 stock setup auto booting into Gnome 2. I killed off Pulseaudio and setup JACK which feeds Jamin and that in turn feeds darkice and rotter. I've tried JACK with the onboard Intel sound card as well as a usb Emu 0202. Both eventually kill darkice so I don't think its necessarily sound card related. The only thing I know for sure is that JACK xruns when darkice crashes, its hard to say whether the xrun causes the crash or the crash causes the xrun (I suspect the latter). When I used darkice 0.2 which is in the repos it would crash within about 12 hours. I installed the latest stable version from source (v1.1) and under pulseaudio it lasted for an average of nearly 4 weeks before crashing. I haven't got much long term data under JACK but it crashes about once a week so far. When it starts crashing, darkice repeatedly disconnects and reconnects to icecast over the course of several minutes until it disappears altogether. I have darkice feeding a local icecast2 server. I was just wondering if there is something I've config'ed stupidly (which is a high possibility) as I keep seeing a lot of people say darkice is rock solid for them too. Here is the darkice config I'm using: http://pastebin.com/ddk7rSjx I have to send a mono 64kbit mp3 out as this is what my streaming provider expects. Any hints would be appreciated even if its the revelation that Ubuntu has known faults and I'm better off using x/y/z distro. I'm also trying to keep the latency down so the internal buffer is only 1 second.

I have four on line stations streaming from RdAirPlay using darkice that have been up and running for over two years with no issues. I use two pcs one to run rivendell and darkice one to run scserv.. The rivendell pc uses jack to plug in jamin on each stream then darkice. There is no sound card in this machine, jack running dummy. Works great, sounds great. Some particulars on what and how you are doing it might make it possible to help.

I'm not sure how it works 24/7 though. I've used a combination of JACK, Jamin, Darkice and Icecast to take care of compression and Internet streaming (I use Icecast2 as a relay to Live365) however I'm not happy with Darkice. It works great for 1 - 3 weeks and then crashes which borks up everything. Somehow this causes Jamin to also crash and JACK to sit there with nothing to do. So far I've got a script that restarts Darkice every evening which meansIlose the Internet stream for a few seconds but at least I don't have a completely dead system when I least expect it. Its a simple cron jobwithkillall darkice, sleep 5 and then the usual darkice -c /path/to/config. Please note that I don't use this with Rivendell its just a PC grabbing audio from a sound card line in. This means I haven't solved the now and next problem yet. In theory you could install this along with Rivendell so long as you're using JACK but I wouldn't recommend it. I have a guide that was meant for internal use only thats available over at: http://www.thevoiceasia.com/rivendell/HOW TO - Multipurpose Broadcast PC.pdf This was setup as an emergency cover machine when my broadcast rack died so its not ideal. It runs on a very early Core 2 dual core PC fromaround2007 without skipping a beat though. The compressor settings I used sound OK for the things we're broadcasting but I'm far from an audio expert so please take these settings with a massive grain of salt. The guide doesn't really list some of the reasons why things are the way they are. The guide also details using Rotter for audio archiving. I hope topolishthis up for the wiki "soon(tm)" but my time is severely limited at the moment.
