Are tickets ever expiring or are the tables just consistently growing? If you have a problem with your ticket registry cleaner your data set will grow and your heap will never fully recover without recycling services. You shouldn’t have to restart nightly if the ticket registry cleaner is removing tickets.

Is there an option to run ticket registry in another JVM?

Try a TGT lifetime of several hours and an ST lifetime of some minutes. But I can't tell the rationale.

If you just can't kill the curiosity, I recommend you saving a snapshot of your Debian GNU/Linux CAS server, then installing xorg, xserver, lightdm, and a lightweight desktop environment of your choice, and visualvm; then fetching your CAS process from visualvm and profit from great stats and insights. When you are satisfied you restore the saved snapshot so finally everything keeps as clean and performant as before the intervention.

JVM Heap args are Xms 4096m & Xmx4096m, but it kept every day. Is there a way to find out whats taking all this space? We are talking about 3000 logins a day. This is pretty much common every day. I was hoping that old tickets get expired and new tickets get created and stay active for 8 hours. If thats working, memory requirement should not keep increasing every day. jvm.memory.heap.usage in stats file kept growing from 3% to 50% within 3 days of uptime. I don't understand why the tickets are not cleaned up/expired. Is there a way to know the no# of tickets..etc ? We disabled /status URI though. What parameters do you guys use for TGT lifetime and ST lifetime? We just use LDAP and hazelcast ticket registry with 5.0.5.
