Ashley, from your numbers the memory consumption seems to be pretty steady, actually, doesn't it? It certainly isn't growing. so maybe you should use a profiler to figure out where the memory is actually consumed. It might just be due to a bug in your implementation. In general I am very sure that your assumptions about percflow are correct.
It may also depend on how you measure memory consumption. Up until now I have found no really reliable way to measure memory consumption in Java, even if you manually call the garbage collector etc. Eric 2008/7/25 Ashley Williams <[EMAIL PROTECTED]>: > > Hi, > > We were looking forward to going to production with our profiling aspect > however when we ran our app through jmap we got the chart pasted below.
