Hi,

  • Are you running Foreman via Forklift or have you installed by yourself?
  • What’s the output of foreman-maintain service status?
  • Can you (re)start the candlepin service?

  1. I have installed myself

  2. [root@XXXXXX ~]# satellite-maintain service status -b

For candlepin it’d be the tomcat service.

Yeah if you keep having issues with tomcat dying, you can share the tomcat failure logs here. Also, consider checking for OOM (out-of-memory) errors in your system logs.
