#Apache lucene causing oracle jvm to die update#

When using Oracle Java 7 or OpenJDK 7, be sure to not use the GA build 147 or update versions u40. JRockit key features were merged into OpenJDK / Oracle Java. Begining with Solr 4.8, Java 7 or greater is required. With out tests Java 11 performed significantly better as compared to java 8. We experimented against java 8 and java 11 specifically.

Oracle seems to no longer accept bugs / only accepts bugs from customers with a paid support contract, so there is no chance for the Lucene Contributors to report bugs upstream.Īs stated by Oracle, it is recommended to upgrade to Oracle Java 7 or OpenJDK 7 (both update 1 or later). G1 is default GC with java 9, however it’s present in Java 8 as well but it was in very early stage and you have to be explicit while defining the same. Oracle JRockit is no longer available for Java 7+, but it is still used in legacy environments (e.g. 192 issues in total 11.0.6 (1 issues): 11.0.6-oracle, ARa JDK-8230706: Waiting on completion of strong nmethod processing causes long pause times with G1. Use -XX:-UseSuperWord if you are running on 7u40 <= JVM < 7u55 Use -XX:+UseMembar if you are running on a JVM < 1.6u18 see this writeup for details in analyzers) crash on certain inputsĬoncurrent Classes suffer from a race in LockSupport park() arising from weak memory models Upgrade to Java 6, use a different JRE vendor, plug in an alternate, more up-to-date XSL engine like Apache XALAN, or set system property telling TransformerFactory to use the non byte-code generating bundled XSL engine in Java 5īreakIterators (e.g. this would shed more light on whether the JVM is somehow hung vs our bug (infinite loop). Xml-query-parser's XSLT transforms fail under some locales Hello, In our solr non-cloud env., we are seeing lots of CLOSEWAIT, causing jvm to stop working with 3 mins of solr start. We really need to improve test infra here, so that each HEARTBEAT we also got 1) full thread stacks and 2) total CPU usage of the process as reported by the ManagementBean APIs.

On 64 bit JREs, reading from files may hang (?) SEGV during indexing, with Java 1.6 64 bit

MMapDirectory won't close files until GC (higher transient disk usage than other FSDir) MMapDirectory returns 0 bytes when used for read/write access in remote ( SMB/CIFS) mount

Locally patch Lucene to load large contiguous byte sequences in chunks A standalone instance has all HBase daemons the Master, RegionServers, and ZooKeeper running in a single JVM persisting to the local filesystem. You hit a false OutOfMemoryException when loading norms in an index with many docs This section describes the setup of a single-node standalone HBase. Available for Java 1. Use FSDirectory or MMapDirectory on Windows Java VisualVM is a visual tool that combines command-line Java Development Kit features with lightweight profiling capabilities for both development, test, and production use-cases. NIOFSDirectory has very poor performance on Windows
