Symptoms

The Ali-Tomcat container suddenly exited.

Solutions

Log on to the Enterprise Distributed Application Service (EDAS) console and start the corresponding application to locate the cause for the abnormal exit of the Ali-Tomcat container.
  • Check whether any error message is contained in /home/admin/tomcat (installation directory)/logs/catalina.out.
  • Check whether the system memory is sufficient. If the system memory is insufficient, the out-of-memory (OOM) kill may be triggered. For more information, search for Linux OOM kill on the Internet. If OOM kill occurs, we recommend that you check the system memory usage and adjust the memory allocation policies.
