Cleaned up the test. Everything passes for me locally.
CouchJS process spawned and not killed on each Reduce Overflow Error
Key: COUCHDB-1246
URL: https://issues.apache.org/jira/browse/COUCHDB-1246
Project: CouchDB
Issue Type: Bug
Components: JavaScript View Server
Affects Versions: 1.1
Environment: Linux Debian Squeeze
[query_server_config]
reduce_limit = true
os_process_limit = 25
Reporter: Michael Newman
Attachments: COUCHDB-1246.patch, COUCHDB-1246.patch, categories,

Running the view attached results in a reduce_overflow_error. For each
reduce_overflow_error a process of /usr/lib/couchdb/bin/couchjs
/usr/share/couchdb/server/main.js starts running. Once this gets to 25, which
is the os_process_limit by default, all views result in a server error:
timeout {gen_server,call,[couch_query_servers,{get_proc,javascript}]}
As far as I can tell, these processes and the non-response from the views
will continue until couch is restarted.

Finally found the delete attachments button. It was like a scavenger hunt. Only

Paul, as we were discussing on IRC, I've a reproducible case where querying a
view just hangs and we get os pool full, blocking subsequent requests.
I attach here a wip patch, which adds an etap test (your patch is making this
test fail).

Thanks Paul. I'll probably be updating the patch one or two times until then.

Using this view, a reduce overflow error is created which spawns a CouchJS
process that doesn't die.

Attachment: COUCHDB-1246.patch
Yeah, this is quite the racy error condition. This patch should fix things
though. Basic idea is that instead of doing a link dance we just monitor every
new os process and remove them when they exit.
Also, couch_os_process's were traping exits and ignoring info messages which
left them open, hence the system build up.
This passes my local tests, but I'm not sure how to write an etap for them.
I'll commit it if someone else can duplicate the fix though.
