OS process error

on prevoius version 1.3.0 i get os_process_error,
{exit_status,1}}

I uninstall my previous version 1.3.0 of CouchDB and installed 1.5.0 for the problem with javascript memory issue and encountered os_process_error.

Platform:
Linux 3.2.0-56-generic #86-Ubuntu SMP Wed Oct 23 09:20:45 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux

Some documents have size more, than 5Mb

Or my function in view is slow? I try os_process_timeout = 600000000, ang get OS Process Error

record from error.log:
