Hi!
OS Centos 7, java -version openjdk version "1.8.0_252"
Updated the version of logstash to 7.16.2, now at startup I get the following
systemctl status logstash:
Dec 24 01:27:08 elk systemd[1]: Unit logstash.service entered failed state.
Dec 24 01:27:08 elk systemd[1]: logstash.service failed.
Dec 24 01:27:08 elk systemd[1]: logstash.service holdoff time over, scheduling restart.
Dec 24 01:27:08 elk systemd[1]: Stopped logstash.
Dec 24 01:27:08 elk systemd[1]: start request repeated too quickly for logstash.service
Dec 24 01:27:08 elk systemd[1]: Failed to start logstash.
Dec 24 01:27:08 elk systemd[1]: Unit logstash.service entered failed state.
Dec 24 01:27:08 elk systemd[1]: logstash.service failed.
Executing the command:
/usr/share/logstash/bin/system-install /etc/logstash/startup.options systemd
did not give the result.
Manually starts without errors:
/usr/share/logstash/bin/logstash
Using bundled JDK: /usr/share/logstash/jdk
OpenJDK 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Sending Logstash logs to /var/log/logstash which is now configured via log4j2.properties

Why doesn't it want to run as a service?
Run with parameters:
/usr/share/logstash/bin/logstash --path.settings /etc/logstash
Gives an error message:
[FATAL] 2021-12-24 02:05:16.675 [main] Logstash - Logstash stopped processing because of an error: (NameError) cannot link Java class org.apache.http.conn.ssl.SSLConnectionSocketFactory, probable missing dependency: 'boolean org.apache.logging.log4j.spi.LoggerContextFactory.isClassLoaderDependent()'
