Question

My Cassandra installation runs on flowing system:

• Linux with Kernel 2.6.32.22
• jna-3.3.0
• Java 1.7.0-b147

Sometimes we are getting following error:

*** glibc detected *** /var/opt/java1.7/bin/java: free(): invalid pointer: 0x00007f66088a6000 ***

Does anyone have similar problems? or maybe some hints?

Answer 1

Probably best to open a JIRA ticket if you can repeat this. I am aware of posts on the mailing list where it is clear that Cassandra is not fully tested or supported on Java 7.

Ben Coverston wrote earlier today: ” Use a version of the Java 6 runtime, Cassandra hasn’t been tested at all with the Java 7 runtime”
