---------------------------------
Summary: ~600MB of untracked string memory
Key: KUDU-2358
URL: https://issues.apache.org/jira/browse/KUDU-2358
Project: Kudu
Issue Type: Improvement
Components: tserver
Affects Versions: 1.8.0
Reporter: Todd Lipcon
Looking at a heap dump of a tserver which has 1.6G of tracked memory, there is
about 800MB of apparently-untracked memory held in std::string objects. Since
libstdcxx doesn't have frame pointers, tcmalloc profiling isn't telling the
stack trace responsible here, but merits further investigation (probably using
a custom-built libstdcxx with frame pointers)
