Bug ID: 1359975
Summary: pmchart run-away mem leak replaying multi-archive when
rewinding
Product: Fedora
Version: 24
Component: pcp
Severity: medium
Assignee: nathans@xxxxxxxxxx
Reporter: mgoodwin@xxxxxxxxxx
QA Contact: extras-qa@xxxxxxxxxxxxxxxxx

Description of problem: pmchart goes into a run-away memory leak and eventually
gets killed by oom killer
Version-Release number of selected component (if applicable): pcp-3.11.4-1 /
F24
How reproducible: easily
Steps to Reproduce:
1. wget http://people.redhat.com/~mgoodwin/pcp/archives/goody.tgz; tar xzf
goody.tgz
2. pmchart -z -a goody -t 10m -O-0 -s 400 -v 400 -geometry 800x450 -c CPU
3. expose time controls, select FAST, press REWIND then press STOP
Actual results: pmtime dialog stops, but pmchart does not scroll and spins out
of control and is eventually killed by oom.
Expected results: pmchart should scroll and stop as per pmtime
Additional info: this only occurs when replaying multiple archives (in the
directory 'goody'). It is not reproducible if those archives are merged with
pmlogextract and we only open the one merged archive.
