I do a clean install on my Debian 9 VPS Server with 4GB RAM and 2 CPUs.

The installation is sucessfull but when I configure any MAVEN project, (On Java 8) I get the following error:

I did some changes but nothing works.

Try 1 (Not Working): Ulimit Configuration

See the current limits of your system, run ulimit -a on the command-line with the user running Jenkins (usually jenkins).

core file size          (blocks, -c) 0
data seg size           (kbytes, -d) unlimited
scheduling priority             (-e) 30
file size               (blocks, -f) unlimited
pending signals                 (-i) 30654
max locked memory       (kbytes, -l) unlimited
max memory size         (kbytes, -m) unlimited
open files                      (-n) 1024
pipe size            (512 bytes, -p) 8
POSIX message queues     (bytes, -q) 819200
real-time priority              (-r) 99
stack size              (kbytes, -s) 8192
cpu time               (seconds, -t) unlimited
max user processes              (-u) 1024
virtual memory          (kbytes, -v) unlimited
file locks                      (-x) unlimited

Increaseasing limits, adding these lines to /etc/security/limits.conf:

jenkins      soft   nofile  4096
jenkins      hard   nofile  8192
jenkins      soft   nproc   30654        
jenkins      hard   nproc   30654

Get The Same Error

Try 2 (Not Working): MAVEN_OPTS

Adding some Options to maven configuration.

-Xmx256m -Xss228k

Get The Same Error

Try 3 (Not Working): Default Task Max

Update Default Task Max

nano /etc/systemd/system.conf

Put the next line into the file

DefaultTasksMax=10000

Reboot the system.

Get The Same Error

I am getting frustrated trying to use an CI Environment on Debian.

Any suggestions? I accept even a new CI server that works similar to jenkins.

Reduce the Thread Stack size.

Access to the configuration Jenkins File at:

nano /etc/default/jenkins

Changing the JAVA_ARGS on deploy:

JAVA_ARGS="-Xmx3584m -XX:MaxPermSize=512m -Xms128m -Xss256k -Djava.awt.headless=true"

(For 4Gb RAM)

Reboot the Jenkins Service:

systemctl restart jenkins

Note: per OP @JPMG Developer's own edit to the question.
