Description
There are two runtime parameters for tcmalloc that will have undefined behavior if mongod is compiled with --use-system-tcmalloc:
"tcmallocAggressiveMemoryDecommit" : 1,
|
"tcmallocMaxTotalThreadCacheBytes" : NumberLong(1073741824),
|
We need to fix the includes in:
src/mongo/util/tcmalloc_set_parameter.cpp
src/mongo/util/tcmalloc_server_status_section.cpp
And ifdef out the extension made to tcmalloc (GetThreadCacheSize())
