Bab,
This is an interesting issue. Couple of questions:

Are you running Tomcats as a published app in Citrix?

After restart, are you seeing another process started on same xenapp
server?Just wondering how is that possible as port is static.

Can you please give more details about the 'stuck' Tomcat process? 3 Thread
dumps in 5sec intervals would be great. From your description it seems that
process entering in hang state. Please use -F switch of jstack to dump
threads.

Are you still able to connect to the hang Tomcat using JMX? What about the
2nd instance, is that accessible via JMX?

Please let us know.

RE: Tomcat service gets stuck

2018-08-22 Thread Louis Zipes 
Hi Bab,
I assume you mean it is getting stuck with a Windows service or not true?

Can you please share logs with the specific error you are seeing.

Thanks, Louis

Subject: Tomcat service gets stuck


- - - external message, proceed with caution - - -

Hi,

I have a problem with tomcat 8.5.20 and 8.5.32.
When I stop the service the PROCESS gets stuck on a specific memory usage.
I cannot even end the task, I have to restart the server.
If I just restart the service, it will create an additional process. The other 
process will remain stuck at the exact same memory usage.
I am using Tomcat on a Citrix environment.

Can you please advice?

Thank you,

Re: Tomcat service gets stuck

2018-08-22 Thread Bab Alemzadeh 
Hi Chris,

I am using Windows Server 2008/2012, datacenter edition.
We have installed: KB4338815.

So the task gets stuck, it is probably not consuming any CPU. But the
memory usage gets stuck.
I enclosed the screenshot, this screenshot is AFTER the tomcat service was
stopped.
The memory usage is still at ,9 MB even though the Tomcat service is
completely stopped!

Thanks,

Can you explain this a little more? What does "stuck on a specific

More information, please.

Citrix is unlikely to be a contributing factor, but thank you for that
information.

I'm assuming this is a Windows environment (Citrix + "service")? Can
you please give us the version details?

Specifically, have you installed KB4338815 or KB4338818?
