For this issue, can logadm command to saftey truncate "milestone-multi-user-server:default.log.0" or setup a command line inside logadm.conf and let O/S to automatic truncate, keep rotate the file...
I found that there was a SMF log file: /var/svc/log/milestone-multi-user-server:default.log.0 which occupied around 19G bytes.
Please help me how to purge this massive file.
Can I just use cat...
