Refer to GPT and own thinking, this problem may be caused by IE object when accessing multiple web pages will produce memory leakage. After each use of an IE object, be sure to clean it up and free up all associated resources. Here are some solutions that might help:
After each web page is loaded, call the Quit method of the IE object, close it and release memory, and then create a new IE object.
Try using IE's headless browsing mode, which will not display IE on the desktop, saving some memory and resources.
Try setting the option for IE to "Open link as a new TAB" so that each new link will open in a new TAB instead of a new window, possibly reducing memory consumption.
Attempts to reduce the length of the interval in order to complete the access task faster and free up memory.
After a certain number of web pages have been visited, restart your computer to free memory.
Anyway, the solution to this problem is probably to try different methods to free up memory and avoid memory leaks.
Network fault: When you access multiple web pages, Internet Explorer may encounter network delay or disconnection. As a result, Internet Explorer cannot load web pages properly. You can use the Ping command or other network tools to check whether the network is normal.
System resource problem: When you access multiple web pages, Internet Explorer may occupy a large number of system resources, causing the system to run slowly or crash. You can use tools such as task manager to check the usage of system resources, such as CPU, memory, and disks.
Security Settings Problem: The security Settings of Internet Explorer may affect web page loading and access, for example, blocking scripts and pop-up Windows. You can check Internet Explorer's security Settings to ensure that they allow you to load and access the content of the web page you want.
