Hi, We are running Solr-Lucene 4.0-SNAPSHOT (1199777M - hudson - 2011-11-09 14:58:50) on severel servers running:
64bit Debian Squeeze (6.0.3) OpenJDK6 (b18-1.8.9-0.1~squeeze1) Tomcat 6.028 (6.0.28-9+squeeze1) Some of the servers have 48G RAM and in that case java have 16G (-Xmx16g) and some of the servers have 96G RAM and in that case java have 48G (-Xmx48G). We are seeing some inconsistent crashes of tomcat's JVM under different Solr/Lucene operations/circumstances. Sadly we can't replicate it. It doesn't happen often, but often enough that we can't rely on it in production. When it happens, something like the following appears in the logs: ========================================================================== # # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f6c318d0902, pid=16516, tid=139772378892032 # # JRE version: 6.0_18-b18 # Java VM: OpenJDK 64-Bit Server VM (14.0-b16 mixed mode linux-amd64 ) # Derivative: IcedTea6 1.8.9 # Distribution: Debian GNU/Linux 6.0.2 (squeeze), package 6b18-1.8.9-0.1~squeeze1 # Problematic frame: # j org.apache.lucene.search.MultiTermQueryWrapperFilter.getDocIdSet(Lorg/apache/lucene/index/IndexReader$AtomicReaderContext;Lorg/apache/lucene/util/Bits;)Lorg/apache/lucene/search/DocIdSet;+193 # # An error report file with more information is saved as: # /tmp/hs_err_pid16516.log # # If you would like to submit a bug report, please include # instructions how to reproduce the bug and visit: # http://icedtea.classpath.org/bugzilla # ========================================================================== Every time it happens the problematic frame is: Problematic frame: # j org.apache.lucene.search.MultiTermQueryWrapperFilter.getDocIdSet(Lorg/apache/lucene/index/IndexReader$AtomicReaderContext;Lorg/apache/lucene/util/Bits; )Lorg/apache/lucene/search/DocIdSet;+193 And /tmp/hs_err_pid16516.log is attached to this mail. Has anyone seen this before? Please don't hesitate to ask for further specification about our setup.
