Downstream Change Summary
New diagnostic feature.
Should be included in 4.4 release notes, and internal knowledge base.
Description of Linked Ticket
We should add some text similar to the following to the manual, where troubleshooters will see it as a tool in the toolbox:
"On Linux (currently supported only for x86-64 architectures), we have introduced a runtime diagnostic feature in v4.3.4+. When a mongod or mongos process receives a SIGUSR2 signal, it will log a backtrace for each of its threads. Such log lines can be piped into buildscripts/mongosymb.py for expansion into more precise code locations."
