Tim Underwood commented on SOLR-12874: -------------------------------------- According to the #openjdk IRC channel the JEP 158 Documentation is wrong and 20M is expected to work: {noformat} [08:08] <tpunder> Anybody know anything about the JEP 158 (Unified JVM Logging) "filesize" argument? JEP 158 says that value is in KB and uses "filesize=1024" as an example for 1MB gc log file sizes. However on both Linux and OS X "filesize=1024" gives me gc log files that are 1024 bytes in length. [08:11] <shade1> I think JEP grammar is incorrect, and UL accepts the usual suffixes (K, M, G), and no-suffix is bytes [08:13] <Maldivia_> tpunder: java -Xlog:help gives this as an example: -Xlog:gc=trace:file=gctrace.txt:uptimemillis,pids:filecount=5,filesize=1m [08:14] <tpunder> Yes, filesize=1M does work. Just wondering why the JEP says it should be KB. [08:15] <shade1> it think it was drafted before implementation and tests [08:15] <shade1> so, mistake (or rather, optimistic typo) in grammar comment [08:16] <tpunder> I specifically ran into a problem upgrading Apache Solr to Java 11 because the launch scripts were setup to use filesize=20000 (they meant wanted 20M) based on the JEP documentation. Manually patching the launch script to filesize=20M works. [08:16] <tpunder> Ok thanks for confirming. {noformat} > Java 9+ GC Log files are being rotated every 20KB instead of every 20MB > ----------------------------------------------------------------------- > > Key: SOLR-12874 > URL: https://issues.apache.org/jira/browse/SOLR-12874 > Project: Solr > Issue Type: Bug > Security Level: Public(Default Security Level.
