Can you try "grep -i 'killed process' /var/log/messages"

Hi,

What is the JRE version? I hope you are not using
ExitOnOutOfMemoryError option [1]. If this is not the case, then my
hunch is some external process is killing the Tomcat and you need to
find it out. In Windows, whenever something like that happens, one
eventlog gets created. I am pretty sure there will be similar thing in
Ubuntu. I just Googled and saw this [2].

Another thing I would suggest, please monitor the memory usage of the
Tomcat process using some tool. Try to identify if it is getting
crashed after reaching to a certain threshold.

Thanks!
Suvendu

Can you try not using Tomcat from the package manager?  Just download for
example
http://www-us.apache.org/dist/tomcat/tomcat-8/v8.5.16/bin/apache-tomcat-8.5.16.zip
put your app in the webapps directory and execute bin/startup.sh

Re: tomcat 8.5.16 silent exit without any error logs on ubuntu 16.04.2

[Greg Huber]

Check /tmp for any dumps,  hs_err_pid.log if there is a jdk issue.

Sometimes jsvc restarts for me :

V  [libjvm.so+0x98f752]  oopDesc*
PSPromotionManager::copy_to_survivor_space(oopDesc*)+0x162

Re: tomcat 8.5.16 silent exit without any error logs on ubuntu 16.04.2

[Guang Chao]

How much RAM your hardware have?  Have you tried installing Tomcat from
download and make it  a service through your own init scripts?  (E.g.
https://gist.github.com/miglen/5590986)
