Robert Newson commented on COUCHDB-613:
---------------------------------------
Hi,
Sorry, I don't currently have any more information than this. I wanted to
report it while I still had what little information I had on screen. CouchDB is
responsive after this event without restarting it but since this happens in my
automated overnight tests I can't say how immediately it recovers.
All I know is that I was left with an incomplete .compact file for every single
database (a dozen or so) on each of the three servers I tested this on and no
active tasks on any of them. I figured that was pretty extraordinary. I agree
that it's not likely that the client issuing the _compact calls or the one
calling _active_tasks is the cause of the crash.
Sorry I don't have more information at this time, I'll be on IRC after I
conduct an interview today and perhaps we can chat about this?

> Project: CouchDB
> Issue Type: Bug
> Components: Database Core
> Affects Versions: 0.11
> Environment: debian 5.0, amd64, couchdb from git.apache.org at

> Reporter: Robert Newson

> I'm running repeated tests where I create multiple databases on multiple
> machines and then compact them all in parallel.
> This almost always works but sometimes does not. Specifically, I have one
> machine where each .compact file is about 50% complete (I know this because I
> see successfully compacted versions of the same data on the other machines in
> my set) and this in the log;
> [Mon, 04 Jan 2010 19:50:23 GMT] [error] [<0.17793.28>] Uncaught error in HTTP
> request: {exit,noproc}
> [Mon, 04 Jan 2010 19:50:26 GMT] [error] [<0.17801.28>] Uncaught error in HTTP

> [Mon, 04 Jan 2010 19:50:26 GMT] [error] [<0.17753.28>] Uncaught error in HTTP
> request: {exit,noproc}
> I'm not sure it's related to the compact process crash but my http client
> also received an error while polling _active_tasks for compaction to complete;
> Waiting for compaction to complete.
> Exception in thread "main" org.apache.http.conn.HttpHostConnectException:
> Connection to http://machine_name:5984 refused
