logback 0.9.8 keeps dropping and recreating connections -------------------------------------------------------

Key: LBGENERAL-16 URL: http://jira.qos.ch/browse/LBGENERAL-16 Project: logback-general Issue Type: Bug Components: build-structure Affects Versions: unspecified Environment: Operating System: All Platform: All Reporter: Joern Huxhorn Assignee: Logback dev list Priority: Blocker

I have a serious problem with logback 0.9.8 that forced me to downgrade to 0.9.7 again. The socket-appender keeps dropping and recreating connections, missing log-events in the process. It does so at least once, i.e. creating a connection without writing a single event and then closing it again immeditaly. I tried to reporduce the behaviour in a simple test program but didn't succeed. Everything is fine in a simple test. In both of our "real" applications, however, this problem is definitly reproducible and just vanishes after a downgrade to 0.9.7. I suspect that the problem is connected to log4j-over-slf4j because that's one of the differences to my small test. We have the following dependencies: <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <scope>compile</scope> </dependency> <dependency> <groupId>commons-logging</groupId> <artifactId>commons-logging</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>jcl104-over-slf4j</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>log4j-over-slf4j</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <scope>provided</scope> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <scope>compile</scope> </dependency> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <scope>compile</scope> </dependency> with slf4j 1.4.3 and logback 0.9.8 as version. We use several third-party jars in our apps, e.g. spring, commons-stuff etc., so we have to map both commons-logging as well as log4j to logback. This worked perfectly up to version 0.9.7 but doesn't work anymore! I'm sorry about this rather obscure error report but I'm really quite clueless about the problem myself. I just checked the svn repos and the last socket appender change was done 4 month ago so that can't be responsible... I'll try to investigate this some more but you might already know what's wrong since you know what changed between 0.9.7 and 0.9.8. The problem exists on at least Windows and Solaris, btw.
