Im kicking off the load and not watching it so I don’t have a timestamp to see where it
occurred. After some mucking around I worked out that adding an extra zero to the following
parameter on both nodes makes the problem has gone away:

write_request_timeout_in_ms: 20000

Whatever that parameter exactly controls, Im pretty sure I don’t want to keep a 20s write
timeout :D but it allows my bulk loads to run for the time being.

The nodes are running on some test VM’s  with xmx/xms set at 1Gb. So are you assuming that
bulk counter row adding/incrementing can cause memory issues? How much memory do you need
to allocate before this category of problem would disappear?
