"He's Dead, Jim!"
You may see the “He’s Dead, Jim!” message if the operating system has terminated the tab’s process due to a lack of memory. Computers rely on memory to run programs. Low amounts of memory can cause programs to run slowly or stop running altogether.
Alternatively, if you terminated the process using Google Chrome's Task Manager, the system's task manager, or with a command line tool, this message will appear as well.
If the page wasn’t ended intentionally, reload the page to continue. If the message continues to appear, try closing inactive tabs or other programs to free up more memory.
Curious about the title? "He's dead, Jim!" is a reference from Star Trek to describe things that are unresponsive. Learn more about "He's dead, Jim!"
