[jira] [Created] (DISPATCH-1215) several memory leaks in
edge-router soak test
michael goulish created DISPATCH-1215:
-----------------------------------------
Summary: several memory leaks in edge-router soak test
Key: DISPATCH-1215
URL: https://issues.apache.org/jira/browse/DISPATCH-1215
Project: Qpid Dispatch
Issue Type: Bug
Reporter: michael goulish
Using recent master code trees (dispatch and proton)...
The test sets up a simple 3-linear router network, A-B-C, and attaches 100 edge routers to A. It then kills one edge router, replaces it, and repeats that kill-and-replace operation 50 times. (At which point I manually killed router A.)
Router A was running under valgrind, and produced the following output:
