comment How do I change my default shell on a domain account
Yes, it is a global parameter that affects all users. In this case, all users who have zsh installed. I am not sure you can restrict this to specific user but I would check idmap uid parameter which might allow you to do that.

comment Tomcat webapps eating all the memory up
In short, the 3 options I mentioned tells JVM to use parallel GC collection in oldgen space and let the JVM decide the amount of heap partitioned between young gen, survivor, and oldgen space. So you need to remove the NewSize and MaxNewSize arguments. If you can run the jmap once you restart and once when you hit the problem and post the results, that would tell us how your JVM heap is used and someone may be able to suggest a better tuning option. Without the details of your JVM heap usage, there is not a whole lot anyone can do to help you.

comment Can't open new port in iptables
@MadHatter I am not the OP. I am responding to your -v comment above. I allow port 80,443 from anywhere to my host. Here is the output of iptables -L -n |egrep '80|443' where you can see the rule. I agree adding -v is good but not necessary in this case. # iptables -L -n |egrep '80|443' ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:80 ACCEPT tcp -- 0.0.0.0/0 0.0.0.0/0 tcp dpt:443

comment Tomcat webapps eating all the memory up
I don't believe they are repeated. I see unique PIDs 17196, 17197, 17198... etc. As mentioned earlier, f you provide config files, startup script etc I listed above someone will be able to help you. Also, none of these processes can grow to 8G since the JVM is capped at 5G+overhead.

comment Tomcat webapps eating all the memory up
Why is that you have so many instances of tomcat running? Doesn't look normal to me. These are individual JVM processes each with MX size set to 5GB so no wonder you run out of memory quick. Please post your server.xml, catalina.properties, web.xml and startup.sh to help spot where the problem is.

comment Is there a way to know why a service is restarted and who did it?
I can think of one other place to look i.e. "/etc/clamav/onupdateexecute.d/" to see if there are any scripts out there which freshclam is supposed to run after update.
