Robert Muir commented on LUCENE-5212: ------------------------------------- I crashed again but with a core file (set 'ulimit -c unlimited'). zip file with core dump and hs_err is here: http://people.apache.org/~rmuir/crash.zip (its too large for JIRA, sorry) For some more context, it always happens fairly early in the test run: so when it doesnt crash at this exact point, you can ^C and run again until it does. Here was my commands with output below: (i tried to simplify the procedure to make it easy to reproduce, but its not easy, it took me quite a few tries) {noformat} # note: we are pulling the exact revision that jenkins failed on, because things have changed in lucene codebase over the weekend!!!! svn co -r 1523179 https://svn.apache.org/repos/asf/lucene/dev/trunk # just go to core tests cd trunk/lucene/core # # now the following two commands: just run again and again until it crashes. # rm -rf ../../.caches/ ant test -Dtests.seed=43A1116E7F98BED4 -Dtests.jvms=1 -Dargs="-XX:-UseCompressedOops -XX:+UseParallelGC" {noformat} Here was the output: {noformat} rmuir@beast:~/workspace/trunk/lucene/core$ rm -rf ../../.caches/ rmuir@beast:~/workspace/trunk/lucene/core$ ant test -Dtests.seed=43A1116E7F98BED4 -Dtests.jvms=1 -Dargs="-XX:-UseCompressedOops -XX:+UseParallelGC" Buildfile: /home/rmuir/workspace/trunk/lucene/core/build.xml -clover.disable: -clover.load: -clover.classpath: -clover.setup: clover: ivy-availability-check: ivy-fail: ivy-configure: [ivy:configure] :: Apache Ivy 2.3.0 - 20130110142753 :: http://ant.apache.org/ivy/ :: [ivy:configure] :: loading settings :: file = /home/rmuir/workspace/trunk/lucene/ivy-settings.xml resolve: init: compile-core: compile-test-framework: ivy-availability-check: ivy-fail: ivy-configure: [ivy:configure] :: loading settings :: file = /home/rmuir/workspace/trunk/lucene/ivy-settings.xml resolve: init: compile-lucene-core: ivy-availability-check: ivy-fail: ivy-configure: [ivy:configure] :: loading settings :: file = /home/rmuir/workspace/trunk/lucene/ivy-settings.xml resolve: init: -clover.disable: -clover.load: -clover.classpath: -clover.setup: clover: compile-core: compile-codecs: [echo] Building codecs... ivy-availability-check: [echo] Building codecs... ivy-fail: ivy-configure: [ivy:configure] :: loading settings :: file = /home/rmuir/workspace/trunk/lucene/ivy-settings.xml resolve: common.init: compile-lucene-core: init: -clover.disable: -clover.load: -clover.classpath: -clover.setup: clover: compile-core: -clover.disable: -clover.load: -clover.classpath: -clover.setup: clover: common.compile-core: compile-core: compile-test: install-junit4-taskdef: validate: test: [junit4:pickseed] Seed property 'tests.seed' already defined: 43A1116E7F98BED4 [mkdir] Created dir: /home/rmuir/workspace/trunk/.caches/test-stats/core [junit4] <JUnit4> says ciao!
