This was seen in at least the following tests (number in parentheses is the number of transport services that crashed during the test): test_transport_api_multi.exe test_core_quota_compliance_symmetric.exe perf_ats_proportional_transport_none.exe (2) perf_ats_proportional_core_none.exe (3) perf_ats_proportional_transport_bandwidth.exe (3) perf_ats_proportional_core_bandwidth.exe (2) perf_ats_proportional_transport_latency.exe (2) perf_ats_proportional_core_latency.exe (2) perf_ats_ril_core_none.exe perf_ats_ril_core_bandwidth.exe (2) perf_ats_ril_transport_latency.exe (3) test_dht_2dtorus.exe (11) test_revocation.exe (2) test_integration_bootstrap_and_connect.py test_integration_disconnect.py  | ||||

	This is caused by start/stop order: During shutdown: GST_neighbours_stop (); GST_validation_stop (); GST_plugins_unload (); So the map is already freed during plugin unload ... Patch is wip...  |
