Hi Clement, The memory used by the RangeServer can controlled by the following config properties:
Hypertable.RangeServer.MemoryLimit Hypertable.RangeServer.MemoryLimit.Percentage The first specifies an absolute limit and the second specifies the limit in terms of a percentage of physical RAM. One thing to keep in mind is that these limits do not account for heap fragmentation. By default, Hypertable uses a MemoryLimitPercentage of 60, which is equivalent to most all of system RAM including heap fragmentation. You might want to try adding the following line to your hypertable.cfg file (push out to all machines and then restart): Hypertable.RangeServer.MemoryLimit.Percentage=40 If that doesn't work, try lowering it further. - Doug P.S.
