I had clients with Tomcat in my test Plesk. I disabled their Tomcats. I noticed the Tomcat doesn't stop. It doesn't stop launching even after reboot. So, it was leaking the RAM and worse performance. Well, what I did is deleted records with 'tomcat' type in DomainServices. It solved the problem. I am in doubt now how about logging and or billing should be correct? should I instead change the psa.sh to correct a condition on starting Tomcat?
