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:
```auto
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:
```auto
/usr/share/logstash/bin/system-install /etc/logstash/startup.options systemd
```
did not give the result.
Manually starts without errors:
```auto
/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
[2021-12-24T01:01:11,737][INFO][logstash.runner] Log4j configuration path used is: /usr/share/logstash/config/log4j2.properties
[2021-12-24T01:01:11,778][INFO][logstash.runner] Starting Logstash {"logstash.version"=>"7.16.2", "jruby.version"=>"jruby 9.2.20.1 (2.5.8) 2021-11-30 2a2962fbd1 OpenJDK 64-Bit Server VM 11.0.13+8 on 11.0.13+8 +indy +jit [linux-x86_64]"}
[2021-12-24T01:01:14,170][INFO][logstash.agent] Successfully started Logstash API endpoint {:port=>9600, :ssl_enabled=>false}
```
Why doesn't it want to run as a service?
Run with parameters:
```auto
/usr/share/logstash/bin/logstash --path.settings /etc/logstash
```
Gives an error message:
```auto
[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()'
```
