URL: https://github.com/apache/couchdb/issues/4439
[NOTE]: # ( ^^ Provide a general summary of the issue in the title above. ^^
)
"OS process timed out" error when trying to open big view. View size is
hundreds of thousands documents and almost 400mb on disc.
[NOTE]: # ( Describe the problem you're encountering. )
[TIP]: # ( Do NOT give us access or passwords to your actual CouchDB! )
## Steps to Reproduce
1. upload big amount of data to some database
2. create view for this database
3. provide simple map function:
```
function (doc) {
emit(doc._id, 1);
}
```
5. save view and wait for index to build
6. try to open the view
7. get the "OS process timed out" error
[NOTE]: # ( Include commands to reproduce, if possible. curl is preferred. )
## Expected Behaviour
view just opens
[NOTE]: # ( Tell us what you expected to happen. )
## Your Environment
[TIP]: # ( Include as many relevant details about your environment as
possible. )
[TIP]: # ( You can paste the output of curl http://YOUR-COUCHDB:5984/ here.
)

I already tried increase os_process_timeout but it didn't affect anything.
