Jonathan Ellis commented on CASSANDRA-4104: ------------------------------------------- Also note that stdout + stderr get logged to /var/log/cassandra/output.log when run normally by the debian packaging. Not sure about the RH packages. > Cassandra appears to hang when JNA enabled and heapsize > free memory > --------------------------------------------------------------------- > > Key: CASSANDRA-4104 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4104 > Project: Cassandra > Issue Type: Bug > Affects Versions: 1.0.8 > Reporter: Joaquin Casares > Priority: Minor > Labels: datastax_qa > > When JNA is enabled heapsize is larger than free memory, all that is printed > out is the classpath, then the printouts stop. > If you hit enter again, you get the commandline, but no Cassandra process is > running. > Tested on both OpenJDK and Oracle Java. > {noformat} > datastax@datastax-image:~/repos/cassandra$ free -m > total used free shared buffers cached > Mem: 2008 740 1267 0 3 54 > -/+ buffers/cache: 682 1326 > Swap: 0 0 0 > datastax@datastax-image:~/repos/cassandra$ sudo bin/cassandra > datastax@datastax-image:~/repos/cassandra$ INFO 14:31:32,520 Logging > initialized > INFO 14:31:32,533 JVM vendor/version: Java HotSpot(TM) 64-Bit Server > VM/1.6.0_31 > INFO 14:31:32,534 Heap size: 1247805440/1247805440 > INFO 14:31:32,534 Classpath: > bin/../conf:bin/../build/classes/main:bin/../build/classes/thrift:bin/../lib/antlr-3.2.jar:bin/../lib/avro-1.4.0-fixes.jar:bin/../lib/avro-1.4.0-sources-fixes.jar:bin/../lib/commons-cli-1.1.jar:bin/../lib/commons-codec-1.2.jar:bin/../lib/commons-lang-2.4.jar:bin/../lib/compress-lzf-0.8.4.jar:bin/../lib/concurrentlinkedhashmap-lru-1.2.jar:bin/../lib/guava-r08.jar:bin/../lib/high-scale-lib-1.1.2.jar:bin/../lib/jackson-core-asl-1.4.0.jar:bin/../lib/jackson-mapper-asl-1.4.0.jar:bin/../lib/jamm-0.2.5.jar:bin/../lib/jline-0.9.94.jar:bin/../lib/jna.jar:bin/../lib/json-simple-1.1.jar:bin/../lib/libthrift-0.6.jar:bin/../lib/log4j-1.2.16.jar:bin/../lib/servlet-api-2.5-20081211.jar:bin/../lib/slf4j-api-1.6.1.jar:bin/../lib/slf4j-log4j12-1.6.1.jar:bin/../lib/snakeyaml-1.6.jar:bin/../lib/snappy-java-1.0.4.1.jar:bin/../lib/jamm-0.2.5.jar > datastax@datastax-image:~/repos/cassandra$ ps auwx | grep cass > datastax 18374 1.0 0.0 13448 904 pts/2 S+ 14:32 0:00 grep > --color=auto cass > {noformat} -- This message is automatically generated by JIRA.
