Subject Help! Serious crash!
Date Wed, 07 Oct 2009 17:38:13 GMT
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 :-(
