Hi Coleen,

I believe this is intermittent and can be temporary (most likely number of 
process local mappings, see my comment in JBS). Therefore ideally, this should 
result in an OOM, not a VM exit - at least when it happens during thread 
creation, which is the most likely scenario.

I believe this can happen when the number of mappings exceeds the allowed 
process limit. One simple maybe stupid approach could be to pre-reserve 
mappings, and release them in this situation to decrease the process local 
mapping counter.

Cheers, Thomas
