Hi Ben,
Thanks for your help.
We have created an issue here:
https://issues.apache.org/jira/browse/CASSANDRA-12706
Let's see if we can get some comments there.

Exceptions whenever compaction happens
Hi,
We are not exactly sure what is causing this problem. But after compaction
happens (after 1 week ttl). We start getting this exception:

We have no idea how to solve this. I am losing sleep over this, please help!
Cassandra: 3.0.9 (also happened in 3.0.8)
Java: Oracle jdk "1.8.0_102"
jemalloc enabled

problem with transactions
Hi, Initially, one “if exists” query was not working on cassandra 3.0.8. Its started working after we downgraded to 2.2.7. Now, there are some more “if exists” queries which are not working on cassandra 2.2.7 in some cases. Is there anybody else facing the same problem with transactions? We are using latest oracle jdk on stock amazon AMI. Regards, Nikhil Sharma
