Abhijit Kangale created LOGBACK-1482: ---------------------------------------- Summary: RollingFileAppender creates .tmp file while creating GZ file at midnight Key: LOGBACK-1482 URL: https://jira.qos.ch/browse/LOGBACK-1482 Project: logback Issue Type: Bug Components: logback-classic Affects Versions: 1.3.0-alpha4 Environment: This is happening in production environment. Reporter: Abhijit Kangale Assignee: Logback dev list Priority: Critical Attachments: logback.xml 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. -rw-r----- 1 iphsubmt iphsubmt 7805929 Aug 11 00:00 submissions-pipeline-metrics-2019-08-10.1.log.gz -rw-r----- 1 iphsubmt iphsubmt 8216 Aug 11 00:34 submissions-pipeline-dead-letters.log -rw-r----- 1 iphsubmt iphsubmt 14956341 Aug 11 14:33 submissions-pipeline-metrics-2019-08-11.0.log.gz -rw-r----- 1 iphsubmt iphsubmt 416634 Aug 12 00:00 submissions-pipeline-2019-08-11.0.log.gz *-rw-r----- 1 iphsubmt iphsubmt 13780 Aug 12 00:00 submissions-pipeline-2019-08-11.0.log2815836846996630.tmp* I have referred all open and closed tickets on this topic but nothing helped to resolve our issue.
