Thanks Dave,

Sorry - I wasn't clear before. It's very possible that if the disk 
filled then it might have been because of logs, etc from other running 
processes. What I'm really curious about is more:

- whether couch will degrade gracefully (warn / terminate / etc) in a 
low disk situation rather than why couch might be taking up disk space
- whether the error logs I saw are consistent with the low disk space theory

RE: What was going on at the time, local processes on the same box were 
sending approx 60 - 100 requests / second in to couch, a mixture of 
mostly document retrievals, but maybe 1 in every 6 requests was a PUT to 
create a document. I'm pretty confident that view creation was not 
happening at the time, I also don't think that compaction would have 
been running either (logs have no mention of compacting, and we are 
logging at info level).
