Hi, I'm using Apollo 8.0 with Carla 0.9.14. I noticed that the logs in the /data/log folder are sometimes not generated. Could you explain under what conditions a module generates a log file? Additionally, how can I debug this issue?

Supporting materials (screenshots, command lines, code/script snippets):

the log dir is determined by GLOG_log_dir env variable.
log file name is determined by module name in BUILD file.
when AINFO, AWARN, AERROR ... macro called will generate a log file if not exist.

I have a log directory with existing old log files, but the issue is that when I launch Apollo again, it doesn't generate a new log file.

the real log file format: {module name}.log.INFO.{datatime}.{pid} , the {module name}.INFO is a symlink to the real file.
if you start a new process, pid will changed, so a new log file will be created, it has always been so.

Sure, I got your point. I checked the real log file. The problem is that Apollo doesn't generate a new real log file. So I just wonder why and how can I fix it.
