Hi, I currently experimenting with CouchDB and run into "os_process_error,{exit_status,0}" error when building my views. I've read that large documents may cause this kind of exceptions - which might be the reason in my case: The total database is ~3.2GB in size and contains ~300k documents. Few documents are up to 15 MB large. Can anyone give me a hint how I can get around those os_process_errors? Please find the error log below. Thanks for your help Marcel [Mon, 18 Oct 2010 19:45:04 GMT] [error] [emulator] Error in process <0.16511.0> with exit value: {{nocatch,{os_process_error,{exit_status,0}}},[{couch_os_process,prompt,2},{couch_query_servers,'-map_docs/2-fun-1-',2},{lists,map,2},{couch_query_servers,map_docs,2},{couch_view_updater,view_compute,2},{couch_view_updater...
