Re: FileAppender append="false" does not truncate the file on startup

[Ralph Goers]

You have both the FileAppender and RollingFileAppender writing to the same 
file. This is certainly going to cause problems. I wouldn't be surprised at all 
if Java causes them to share the same OS  File and stream objects so only one 
of the ones Java requests actually works.  If it didn't do these you would 
almost certainly end up with a corrupted output file.

 I expect app.log to be truncated on my application startup.
 
 This is not the case. It is never truncated. Please help

Can you provide your full configuration? (You may want to raise a Jira ticket 
to track this issue.)

To confirm, the actual behaviour is that log4j appends to the end of the 
existing app.log file, is that correct?

Can you also add status=“DEBUG” to your configuration and provide that? I’d 
like to see what is being passed through the configuration.
