[BUG] 运行一段时间后间歇性出现ExternalResourceLeak报错

[ReinWD]

bot发送图片达到一定数量后，mirai控制台输出警告信息显示可能出现资源泄露情况 服务器内存占用随进程运行不断升高

复现

1. 部署mirai-2.7-RC-dev-3
2. 部署HoshinoBot，连接使用 ws_reverse: localhost:8080,res目录 需要单独下载后部署至HoshinoBot同级目录，包含游戏机器人所需要的图片信息
3. 在hoshinoBot中安装插件pokemanpcr
4. 在群组内发送“查看仓库”指令，会收到bot返回的截图信息
5. 发送图片次数达到一定数量后，间隔一段时间会报错一次

版本

onebot-0.3.4- all

mirai-core-2.7-RC-dev-3-all

mirai-console-2.7-RC-dev-3-all

服务器内存只有1GB mirai进程在报错时实际占用 25.4%， 重启后实际占用20.5%，重启前uptime 2天左右

log中只截取了两份完整片段及两个间歇性报错的时间点，聊天内容隐去

最后两段上下文都是正常的文字聊天记录
