Can you send us the stack trace which you can find in the hs_err_pid*.log? is the system memory all used up (free)? any errors in the logs just before the crash? Regards, On Mon, Mar 26, 2012 at 12:35 AM, Maciej Miklas wrote: > I have row cache - it's about 20GB big in this case. > The proble

I have row cache - it's about 20GB big in this case. The problem can be reproduced with our load test - we are using 20 reader threads on single Cassandra node. I will retest it with Java 6 - still it looks to me like JNA problem and JDK in this case should not matter, but we will see. On Thu, M

Use a version of the Java 6 runtime, Cassandra hasn't been tested at all with the Java 7 runtime. On Thu, Mar 22, 2012 at 1:27 PM, Benoit Perroud wrote: > Sounds like a race condition in the off heap caching while calling > Unsafe.free(). > > Do you use cache ? What is your use case when you enc

Sounds like a race condition in the off heap caching while calling Unsafe.free(). Do you use cache ? What is your use case when you encounter this error ? Are you able to reproduce it ? 2012/3/22 Maciej Miklas : > Hi *, > > My Cassandra installation runs on flowing system: > > Linux with Kernel

This looks like a bug (https://issues.apache.org/jira/browse/CASSANDRA-2376), but not one that would cause a crash. Actual process death is only caused by (a) running out of memory or (2) JVM bugs. On Wed, Mar 23, 2011 at 9:17 PM, Sanjeev Kulkarni wrote: > Hey guys, > I have a one node system(wit

Hey Jonathan, Thanks for the reply. I was earlier running 0.7.2 and upgraded it to 0.7.3. Looks like I had to run the nodetool scrub command to sanitize the sstables because of the bloomfilter bug.
