I don't think it's caused by CASSANDRA-8211, because it happens during the
first compaction that takes place between the first 2 SSTables to get flushed
from an initially empty column family.
Also, I've only been able to reproduce it when using both *hsha* for the rpc
server and *offheap_objects* for memtable allocation. If I switch either to
sync or to offheap_buffers or heap_buffers then I cannot reproduce the problem.
Also under the same circumstances I'm pretty sure I've seen incorrect data
being returned to a client multiget_slice request before any SSTables had been
flushed yet, so I presume this is corruption that happens before any
flush/compaction takes place.
nodetool scrub yielded these errors:

[~xedin] That NPE happend once and unfortunatelly I have not saved it. If I'll
get it once more I'll save this sstable.
I totally removed OpsCenter keyspace (with sstables) and recreated them. I
don't get Last written key DecoratedKey any more. By the way, this error
definetely causees streams to hang on 100%.
I have several strange things happening now:
- I've noticed that it takes about 30 minutes between nodetool repair and
first pending AntiEntropySession. Is that ok?
- Repair is already running for 24 hours (~13GB per node, 17 nodes). What's
the number of AntiEntropySessions to finish single repair? Number of key ranges?

It looks like this is not fixed in 2.1.0. We have cassandra under heavy load

We'll try to switch to sync and see what will happen.
Is it possible that streaming hangs because of that exception? Is it possible
that this exception affect minor compactions of other keyspaces?

We should be able to force the problem to occur by artificially delaying the commit log write to prove this. Either way, I don't think Viktor's patch is the best way to deal with this problem, as it leaves cleaning up the direct buffers to GC.

Whereas pycassa generates tuuids like this: 913d7fea-a631-11e3-8080-808080808080, the nonsensical column names look like this: 22050aa4-de11-e380-8080-80808080800b and this: 10c326eb-86a4-e211-e380-808080808080. Most are of the first form. By shifting these nonsensical tuuids to the left or right by 2 octets, you get a reasonable tuuid.

I suspect that may not be everything, though, as these two races probably won't cause the problem often. These are predicated on the assumption that thrift doesn't copy data from the DirectByteBuffer that the hsha server provides to it, so could be wrong, but anyway: 1) CL appends can be lagged behind the memtable update and, as a result, the acknowledgment to the client of success writing. If the CL record contains the ByteBuffer when it is freed, and that address is then reused in another allocation, it will write incorrect data to the commit log. 2) I believe thrift calls are two stage. If this is the case, and the client disconnects in between sending the first stage and receiving the result in the second stage, the buffer could be freed whilst still in flight to the memtable/CL These are just quick ideas for where it might be, I haven't familiarised myself fully with thrift, the disruptor etc. to be certain if these are plausible, but it may turn out to be useful so thought I'd share. was (Author: benedict): So, I think there may potentially be at least two races in the off heap deallocation.
