Sounds like zdbbl.. I'm running 1.3.1 but it started after added 6 more
nodes to the previously 12 node cluster. So maybe it is because of a 18
node cluster?
I'll try the zdbbl stuff. Any other hint would be cool (if the new
kernel parameters are also good for 1.3.1.. could you provide them?).
Cheers
Simon
