Running Mongo 3.6.20 w/ WiredTiger 3.2.1?


We run Mongo 3.6.20 (yes, working towards running 4.X) and are encountering a bug in WiredTiger 3.1.1 that appears to have been fixed in WT 3.2.1 based on the bug tracker.
I’ve looked at the upgrade guide for WiredTiger ( and I don’t believe we violate any of the concerns listed.

Has anyone run Mongo with an upgraded WiredTiger dependency?
We already build our own binaries so there’s not a meaningful overhead for modifying the source.


It may compile (haven’t tried), but the biggest risk is of course that each version of MongoDB vendors and tests with a specific snapshot of the WT library. I would certainly not recommend this configuration.
