[jira] [Resolved] (TS-4004) ASAN crash while running regression
test Cache_vol
[ https://issues.apache.org/jira/browse/TS-4004?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bryan Call resolved TS-4004.
----------------------------
Resolution: Fixed
Works now:
{code}
[bcall@homer trafficserver]$ sudo /usr/local/bin/traffic_server -f -R 1 -r Cache_vol
traffic_server: using root directory '/usr/local'
REGRESSION_TEST initialization begun
REGRESSION TEST Cache_vol started
RPRINT Cache_vol: 1 128 Megabyte Volumes
RPRINT Cache_vol: Not enough space for 10 volume
RPRINT Cache_vol: Random Volumes after clearing the disks
RPRINT Cache_vol: volume=1 scheme=http size=128
RPRINT Cache_vol: Random Volumes without clearing the disks
RPRINT Cache_vol: volume=1 scheme=rtsp size=128
REGRESSION_RESULT Cache_vol: PASSED
REGRESSION_TEST DONE: PASSED
