Summary: CronTriggeringPolicy timing / file deletion issue
Key: LOG4J2-1480
URL: https://issues.apache.org/jira/browse/LOG4J2-1480
Project: Log4j 2
Issue Type: Bug
Affects Versions: 2.6.2
Environment: 2013 macbook pro running OSX El Capitan. Log4j2 is
running as a module dependency to a bigger Vertx server project.
Reporter: matthew beckham
Most of this issue is outlined in this stack overflow post:
http://stackoverflow.com/questions/38514101/log4j2-default-rollover-strategy-deleting-new-log-files
This details my attempt to use the CronTriggeringPolicy to rollover a log file.
My longterm goal was to have it roll over every 15 minutes, but used 1 minutes
intervals for testing (I did also try with 3 and 5 minute intervals with the
same outcome).
The gist of the issue is that after the first triggering of the cron triggering
policy (which happens at the correct time), the rollover mechanism will
disregard the cron schedule in place and attempt to rollover every second. In
addition to this, the log file that is created from a rollover can be deleted
immediately after it is created. The log file appears to not get deleted if
there is a iterator argument (%i) in the file name though.
I don't know if these are two separate issues, or if the file deletion is a
side effect of the cron scheduling getting messed up.
For now I have switched to using TimeBasedTriggeringPolicy and that appears to
be working correctly at the moment.
Logs and sample configuration code can be found in the linked stack overflow
post.
