I'm hitting the following OverlappingFileLockException in LogBack. Is there any know issues with prudent mode in this version of Logback?

I use logback to compress logfiles. But excessive CPU utilization by compressing log files affects the execution efficiency of business code.
How to limit the CPU utilization of logback compressed files

I need guidance for a logging requirement I am having.
My application got two services - upload and download.
I need to maintain separate logs for both - So far I have done below in logback.xml

<file>download.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">

Usage of defined loggers in application is used by respective service classes.
ie classes of upload service obtain logger by
LoggerFactory.getLogger("UploadLogger")
and vice-versa for DownloadLogger.
Upon running the service I notice that only upload.log is created and filled in.
download.log gets created but no content are logged in it .
I suspect usage of filter is incorrect but I couldn't find any solution yet such that both log files can be maintained properly.
Can someone please help me how to correct the config?
The above config is fit for the purpose. The problem was in the way logback.xml was provided as command line argument.
The problem was resolved after providing logback.xml with -Dlogback.configurationFile
When the load is running the logs are not generated in order as per timestamp.
We are using the below logback configuration:
<appender name="messageResponse" class="ch.qos.logback.core.rolling.RollingFileAppender">
<append>true</append>
<file>message-response.log</file>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

I try to use logback for a project and want to have a classic daily rollover.
I cant make it work : all logs keep in the default file.
Either I badly understood the rolling policy, or it dont work corectly. In fact I thought that I I run for instance my tomcat one minute after the last log, the "current" log file is backed up in another file...
For test purpose I tried a "minutely" rollover. Someone see something horrible in my config ? :
<appender name="dailyRollingFileAppender"
class="ch.qos.logback.core.rolling.RollingFileAppender">
<File>C:/myProject/programs/apache-tomcat-8.0.21-presentation/logs/presentation-log.log
</File>
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<!-- daily rollover -->
<FileNamePattern>C:/myProject/programs/apache-tomcat-8.0.21-presentation/logs/presentation-log.%d{yyyy-MM-dd_HH-mm}.log</FileNamePattern>
<timeBasedFileNamingAndTriggeringPolicy
class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
<maxFileSize>10MB</maxFileSize>
</timeBasedFileNamingAndTriggeringPolicy>
<!-- keep 1 day history -->
<maxHistory>1</maxHistory>
<cleanHistoryOnStart>true</cleanHistoryOnStart>
</rollingPolicy>

In my application is using RolingFileAppender with size based triggering policy main classes initializes log file using logback configuration file. When main class is invoked using a shell script, I see log messages are correctly going to log file that conf define but in addition it also created empty logfile with scriptname
say ABC.sh calls MainClass which is supposed to write to logback123.log now all messages are going to logback123.log fine but there is extra empty ABC.log file is getting created.
Any thoughts on this
