Tom,
you should look at phi_convict_threshold and try and increase the value if

Thanks

there are no hints. But whenever it happens, the hints are quickly piling
up. This results in heap problems on the node (Heap is 0.813462 full...
appears many times). This in turn results in the flushing of the
