【TDengine 使用环境】
生产环境 /测试/ Poc/预生产环境
目前在测试环境k8s上面进行试用部署
【TDengine 版本】
3.3.6.1
【操作系统以及版本】
k8s容器部署
【部署方式】容器/非容器部署
在k8s通过自己创建或yaml文件部署
【遇到的问题：问题现象及影响】

现象:
通过taosd启动后的命令行打印的:

自己都将这些问题问了AI:按照AI给的解决方案,执行了这些操作:
ps -ef | grep taosd
pkill -9 taosd
ls -l /var/lib/taos/.running
rm -f /var/lib/taos/.running
taosd再次启动后,能正常启动一会儿,然后6030 6041 6044端口又自己停了
