That's once in few days, so I don't think it's too important. Especially
since 0.77 is much better than 0.99 I've seen sometimes :)

You are running into GC issues.
WARN [ScheduledTasks:1] 2012-01-22 12:53:42,804 GCInspector.java
(line 146) Heap is 0.7767292149986439 full. You may need to reduce
memtable and/or cache sizes. Cassandra will now flush up to the two
largest memtables to free up memory. Adjust
flush_largest_memtables_at threshold in cassandra.yaml if you don't
want Cassandra to do this automatically
Can you reduce the size of the caches ?
As you are under low load, does it correlate with compaction or repair
processes ? Check node tool compactioninfo
Do you have wide rows ? Checlk the max row size with nodetool cfstats.
Also, if you have made any changes to the default memory and gc
settings try reverting them.
