附我现在正在使用的临时解决办法，使用了crontab任务

#!/bin/sh

# Path to log file
LOG_FILE="/var/log/ua3f.log"
# Keyword to search for in the log
KEYWORD="too many open"

# Check if the log file exists
if [ -f "$LOG_FILE" ]; then
    # Get the last line of the log file
    LAST_LINE=$(tail -n 1 "$LOG_FILE")

    # Check if the last line contains the keyword
    case "$LAST_LINE" in
        *"$KEYWORD"*)
            # Get the current timestamp in the format YYYY-MM-DD-HH-mm-SS
            TIMESTAMP=$(date +"%Y-%m-%d-%H-%M-%S")

            # Path to new log file in /root/ua3f/
            NEW_LOG_FILE="/root/ua3f/ua3f-$TIMESTAMP.log"

            # Move the original log file to the new location and rename it
            mv "$LOG_FILE" "$NEW_LOG_FILE"

            # Delete the original log file
            rm -f "$LOG_FILE"

            # Restart the ua3f service
            service ua3f restart
            ;;
    esac

如果启动 UA3F 短时间内出现大量日志，说明出现流量回环，你需要检查你的 Clash 配置，让 Clash 不要接管本机网络流量
