Bug 934389 – dev-db/mongodb-5.0.26: randomly rans out of fds and crashes, when running dev-python/pymongo test suite

• Status: CONFIRMED
• Product: Gentoo Linux

I'm pretty sure tests used to pass before.  Now, at a random point mongod crashes (and therefore they start failing).  The log indicates:

Ping.  This is making it impossible to test dev-python/pymongo.
