[aspectj-users] Memory consumption problems

[Ashley Williams <ashley.williams@xxxxxx>]

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. So it looks like some aspectj objects
are responsible for a sizable share of memory. Without knowing more about
them and if they will consume more memory with time, we can't proceed any
further.

The aspect we have created contains
a stopwatch implementation and a logger and its cardinality is percflow
so we get one per service method call on our server. I was under the impression
though that as soon as the method call is finished any aspectj resources
associated are eligable for garbage collection.

I would appreciate it if somebody could
shed some light on this.

Cheers
