[jira] [Commented] (SOLR-12874) Java 9+ GC Log files are being
rotated every 20KB instead of every 20MB
[ https://issues.apache.org/jira/browse/SOLR-12874?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16650900#comment-16650900 ]
Shawn Heisey commented on SOLR-12874:
-------------------------------------
Is 20M properly interpreted by Java 8? If not, we'll need different options for different java versions.
Sounds like there needs to be a bug filed against Java, because all of Oracle's documentation that I've been able to locate indicates that the number should be interpreted as kilobytes if a unit is not provided.

> The Java 9+ GC logging options in bin/solr and bin/solr.cmd specify a log rotation file size of 20000 which according to JEP 158 ([https://openjdk.java.net/jeps/158]) should be the "file size in kb" however when running Solr on Java 11 I'm seeing GC logs rotated every 20KB.
> Changing "filesize=20000" to "filesize=20M" fixes the problem for me under Linux.
