little more background,
4 machine cluster with replicatin_level =1,
jvm set to 6G (I've tried with jvm at 12 and 18 to same effect)
on boxes swappiness is set to 0
for disks I have 3PAR iSCSI mounts of 500GB each

Looks like you had a big GC that caused the reads to back up and the JVM was running out of memory.
What kind of writes per second were you seeing? How many solr cores?
from solandra.
UPDATE
Turning off row_cache completely and disabling swap I was able to ingest using one of the 4 nodes for about 15 hours and counting, and just started ingesting on a second node, and keep getting this error frequently -
