Automic Workload Automation

Hey everyone,

we're testing the new Automation Engine 12 with the Automic Web Interface 12.1.1.

We've the problem that the Tomcat 7 service "tomcat7.exe" is using 100% of the CPU. The problem exists until we're restarting the service and happens in irregular intervals.

Does somebody of you have the same issue or an idea how we can analye or solve this issue?

Thanks in advance,

Best regards,
Tobias 

Hi.

We have not seen this particular issue.

Have you tried setting the logging level to "FINE" (Tomcat's equivalent of a DEBUG logging level)?
https://tomcat.apache.org/tomcat-7.0-doc/logging.html

Beyond that, on Linux, I'd recommend you use strace, but since we're probably talking Windows (judging by the tomcat7.exe), the closest equivalent is probably:

Disclaimer: I have never used it myself, but it appears to be the closest analog to strace, and therefore your best shot at finding out what kernel calls it makes when it gets to 100% CPU loads, and making assumptions about the underlying cause, from a user perspective and without having source code.

If you have an Eclipse IDE handy, you can also try to attach it as a debugger:
