Critical - P2 Description
We've been testing some of our routing mapReduces in 3.2 RC4 and have a reproducible segfault that occurs on both Windows and CentOS7. The attached script works fine in 3.0 WT but crashes consistently in 3.2 RC4 WT.
For information, this script collapses documents into daily-groups and is a relatively simple MR process.
Steps to reproduce
- Restore the data from here: https://dl.dropboxusercontent.com/u/map_reduce_anon.js6076108/routeResult_anonymised.bson.gz
- Run the attached script: (mongo <dbname> map_reduce_anon.js)
- MongoD will crash after a few seconds
The Windows build does not write the crash details into the log, but the CentOS version does:
