Description
之前用其他时序库，存储几年数据或者偶然插入一些100年以后时间的数据，运行查询时会导致服务假死。当时分析原因是文件句柄超过系统默认限制，时区库数据按文件存储，假如查询条件中时间跨度大或全表扫描时，会导致占用很多文件句柄，导致超限。Dengine会有类似的问题吗？

Research direction
The issue describes possible file-descriptor exhaustion during broad time-range queries or scans, especially with timestamps far in the future, but names no files, tests, or entry points. Start by checking whether TDengine can reproduce the reported hang under those query conditions; done means determining whether the behavior exists and documenting the result or a concrete tracking path.
