DDT metric memory leakage
Leon investigated a memory leak in the buffer nodes, and it seemed to stem from the DDT metrics ( ECL 73541 ). Martin suggested that turning off the DDT metrics as reported to Ganglia might be a solution. Any understanding as to where the memory leak stems from would be very productive in preventing problems like this in the future. Aim is to eliminate this memory leak by identifying the problem, or, as Martin suggests (and if no other systems would be adversely affected) by disabling the offending block of code.
