>
> I have a few problematic nodes in my cluster that will crash OutOfMemory very
> often. This is Cassandra 0.7.3 downloaded from Hudson.
> Heap size is 6GB, server memory is 8GB.
> Memtable are flushed at 64MB, I have 5 CFs.
> FlushLargestMemtablesAt is set at 0.8 but doesn't help with this issue.
> I will attach a screenshot showing my issue. There is no compaction going on
> when the heap usage start increasing like crazy.
> It could be a configuration issue but it kinda looks like a bug to me.
