研究方向

The issue reports that sending USR2 signal to the main process does not release log file descriptors, causing an increase over time. To reproduce, one would need to set up a supervisor environment with logging and repeatedly send USR2 signals. Investigation should focus on the USR2 signal handler in supervisor, likely in supervisor/supervisord.py or supervisor/options.py, and how it reopens log files. Check if file descriptors are being closed properly during log rotation. Look for any open file handles in loggers or child process management. The minimal information provided suggests that the bug may be intermittent or hardware specific.
