I am getting some problem at cassandra startup. The details of the exceptios is as follows:-
INFO 06:49:10 Initializing system.sstable_activity
ERROR 06:49:10 Exiting due to error while processing commit log during initialization.
java.lang.InternalError: a fault occurred in a recent unsafe memory access operation in compiled Java code

What can be the reason for this ?
I fixed this issue by deleting a commit log that was causing the issue.
I found the log in /casandra/data/commitlog .
After I deleted, I re-ran cassandra and all was well. I hope this helps someone!
