-----------------------------------
Summary: File rollover fails with error due to invalid previous
file log names
Key: LOG4J2-2039
URL: https://issues.apache.org/jira/browse/LOG4J2-2039
Project: Log4j 2
Issue Type: Bug
Affects Versions: 2.8.2
Reporter: Leon Finker
Hi,
Not sure if you want to fix this or not. I noticed the following error and logs
fail to rollover and causes a problem. It could cause a problem i guess if
someone makes some kind of mistake of file suffix during support. Maybe you
want to just skip those invalid files? It seems like it was a recent log4j2
change (maybe 2.8.x) since these files have been there since 2016 and previous
log4j2 versions didn't complain. Looks like maybe support renamed some previous
log files to have unix system time in the suffix like file.log.1457052422478.
