Version 0.8.6.
After an extreme load to 4 (embedded) cassandra servers with replication
factor 3 ( Ubuntu 10.4, dual six core, 64 bit, no swap, 1 15000 rpm
commitlog disk, 1 15000 rpm datafile disk, ) I get a fatal exception as
listed below.
No more messages were found after that.
Probably other things are going wrong like the message "410 Could not
complete hinted handoff to /xxx.yyy.zzz.60", or the Dead/Up messages
(occurring long before this exception).
But maybe this exception can point me in the right direction or even
point out some bug in Cassandra.
Thanks,
Ignace
