In a recent patch build, I noticed that the hang analyzer included the backtraces for the gdb process in the generated archive:
debugger_gdb.log debugger_gdb_21307.log debugger_gdb_21307_raw_stacks.log debugger_mongo.log debugger_mongod.log debugger_mongod_8100.log debugger_mongod_8100_raw_stacks.log debugger_mongod_8221.log debugger_mongod_8221_raw_stacks.log ...
Our custom GDB commands called by the hang analyzer generally assume that the target process is a
{mongo}binary - this results in Python errors logged in the
{debugger_gdb_N.log}files:
