----------------------------
Summary: Does not delete old TrackerContinuation while re-setting proxy.config.dump_mem_info_frequency
Key: TS-4028
URL: https://issues.apache.org/jira/browse/TS-4028
Project: Traffic Server
Issue Type: Bug
Reporter: Oknet Xu
the below command will make a call to init_memory_tracker():
traffic_line -s proxy.config.dump_mem_info_frequency -v 1
a new TrackerContinuation will be created in init_memory_tracker(), but the old one doesn't delete / release.
