particularly the:
* mmap limit which is really what this looks like...

My sstable size is 192MB. I removed some data directories to reduce the
data that need to load, and this time it worked, so I was sure this was
because of the data was too large.
I tried to tune the JVM parameters, like heap size or stack size, but
didn't help. I finally got it resolved by add some
What is your sstable size set to for each of the sstables, using LCS? Are you
at the default of 5 MB?
