The Release team would like for this investigation to gate 8.0 release readiness. We have observed some number of GC-related crashes in mongod and the mongo shell while running SpiderMonkey 91 ESR. We have continued to observe these GC-related crashes after the SpiderMonkey 115 ESR upgrade (SERVER-64574). We should identify whether there is a problem in our embedding and usage of SpiderMonkey, or if there is an issue within SpiderMonkey itself.
