# Why does my Ace Linux Instance keep stopping? If your instance is overused, it may fail health checks. If you over-utilize resources, there are several reasons why your health check might fail. There are a few common reasons for an instance's inactivity: * **CPU**: All the preceding processes necessitate CPU time to work. The kernel cannot perform standard operating system activities if the CPU is used at 100% for an extended period of time. * **Networking**: Your system won't be able to respond to ARP requests from status checks without networking. If this happens, your instance cannot communicate with other hosts. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
