Always OutOfMemory Exceptions makes Jira Software unstable

[Michael_Klennert]

during and after installation of jira software I became after some minutes or days outOfMemory Exceptions.

My details:

Jira Software Version: 8.8.0

Application Server Container: Apache Tomcat/8.5.42
database: mysql57

OS: Ubuntu 18.04.4 LTS x86_64
Kernel: 4.15.0 
CPU: Intel Xeon E5-2680 v3 (16) @ 1.999GHz
Memory: 32768MiB

I tried following solutions:

in '/opt/atlassian/jira/bin/setenv.sh' increased memory usage to:

JVM_MINIMUM_MEMORY="2048m"
JVM_MAXIMUM_MEMORY="4096m"

in '/etc/security/limits.conf' increased user (jira8 after 8 retries of installations) memory to:

jira8 soft nofile 4096
jira8 hard nofile 8192
jira8 soft nproc 4096
jira8 hard nproc 8192

check with shell:

su jira8

$ ulimit -n
4096

the Exceptions makes working with jira impossible. Please help

Found solution for my problem:

my host provider strato installed the OS in the VM with the following default config:

$> systemctl show --property=DefaultTasksMax

195

Now I increased/changed the property value up to 4192 in:

$> vi /etc/systemd/system.conf

DefaultTasksMax=4192

After restart the OS Jira Software runs stable and doesn't create any Thread problems.

@Michael_Klennert  You should mark this as accepted solution so that others could use. Glad that you are able to solve  your problem.

Kind regards,

Hi,

Is the machine physical or virtual. What hypervisor are you using if virtual?

[Michael_Klennert]

It's a virtual machine from Strato provider. I think it is Hyper-V from Microsoft or VMware
