After migrating our servers to openjdk11 we started observing this issue.

We are using below configuration currently. We started using the latest versions of logback and slf4j.

<version.java>11</version.java>

<version.logback>1.3.0-alpha4</version.logback>

<version.slf4j>1.8.0-beta4</version.slf4j>

<dependency>

<groupId>ch.qos.logback</groupId>

<artifactId>logback-classic</artifactId>

<version>${version.logback}</version>

<scope>runtime</scope>

</dependency>

<dependency>

<groupId>org.slf4j</groupId>

<artifactId>log4j-over-slf4j</artifactId>

<version>${version.slf4j}</version>

<scope>runtime</scope>

</dependency>

 

We are using 

SizeAndTimeBasedRollingPolicy as rolling policy and rollover is set at midnight. 

 

Basically the roll over happens properly creating .gz file but at the same time it creates .tmp file for application log.

I have referred all open and closed tickets on this topic but nothing helped to resolve our issue. So please. I have attached logbook.xml file we are using.
