WiredTiger storage engine does not support 32bit architectures. It is designed for modern server architectures.
"There's some key/value encoding we do in WiredTiger that currently requires a size_t be at least 8B."

How does that impact mongodb support?
WiredTiger a new data storage engine. But it is optional, so mongodb will use the old storage engine on unsupported arches.
Note also that I have learned the hard way that MongoDB does not support using the external shared WiredTiger library...
So currently the wiredtiger 2.6.1 packages present in Fedora against which mongodb 3.0.4 has been built seem to mostly work, but updating mongodb to 3.0.6 while still using that latest wiredtiger release breaks runtime pretty badly (the "show dbs" command no longer works, meaning that backup tools don't either, etc.)
yes MongoDB don't work with external WiredTiger. I was trying to create patches to have this working. But I had found a patch and with following version it was broken again. In my point of view it was unmaintainable.
So I've created FPC ticker allow bundling WT library - https://fedorahosted.org/fpc/ticket/562 and temporarily disabled WT support in MongoDB 3.0.6 (it shoudl be in F23 and Rawhide now).
Bundling WT should solve this problem...
This is a dead package now.
