What version are you running? Take 0.4 from trunk.
Default config has
  <CommitLogRotationThresholdInMB>128</CommitLogRotationThresholdInMB>
Did you change it allow your commit log chunks be 1Gb?

Hi guys,

I have a small setup with 3 macs running os x snow leopard and the native java 1.6.0.something.something ;-)
I am doing a lot of inserts, without any problems and I can read the data again.

But....
At some point, around 1G Commitlog size, cassandra starts a rise in ram usage, untill it just stops responding - if I restart the server, with or without -b, it will just usae 100% cpu for 10-15 mins and then stop with this message:
Another problem, is that it seems to kill other servers too, when I try to restart :-(
