Jira software keep crashing

[Fractal Fox Missler]

Hi,
my Jira instance keeps on crashing when there are project management actions taken. I've tried to fix the issue by limiting RAM usage, reinstalling, updating, removing plugins but it's still crashing. I run it on Debian 9 (Stretch) with 2 GiB of RAM, using Apache and running Jira 8.12.1 as a service, mySQL database. Maybe running it on OVHcloud VPS is an issue? I'm not an experienced user in setting up services like that although I've tried my best and still there is an issue with stability. Attaching support zip to help verify the issue.

Problem solved.
The issue was Tomcat crashing.
I've managed to solve the issue by:

- Setting maxHttpHeaderSize="1048576" attribute on the Connector node in server.xml.

-Removing 

 <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on"/>

in server.xml
