@paul-griffith, @Kevin.Herron  
is there any plan to upgrade Ignition **logback 1.2.3** to **logback 1.3.x or 1.4.x**?

I try to add a builtin **DuplicateMessageFilter** to avoid **some repetitive logs** , but it has no effect and seem to be available only from logback 1.3.0 😭

**Ignition/data/logback.xml**

```auto
<configuration> 
    ...
    <turboFilter 
      class="ch.qos.logback.classic.turbo.DuplicateMessageFilter">
        <AllowedRepetitions>3</AllowedRepetitions>
		<CacheSize>100</CacheSize>
    </turboFilter>

</configuration>

```

🤔 seems to be available in **logback-classic-1.2.3.jar** used by Ignition 8.1

the issue must be relative to anything else ...

```auto
	loggerName = "ESSAI"
	log = system.util.getLogger(loggerName)
	for i in range(50):
		log.info("message repetitif")

```

produce all the message in the gateway logs.

No special log from logback at gateway restart

No. I have not run some test with the last version of ignition. Logback has been upgraded since but I don't known if it change anything for this use case.
