Is there any way to get the maximum heap size from inside java. I though that
Runtime.totalMemory() would return that, but it does not. I current am running
one vm with -mx50m and totalMemory() is returning 5242872, which is about 5mb
not 50mb... unless I am totally crazy.
I am running into a problem where my vm grows too big, to fast (faster than the
consumers of the collected data can consume it), resulting in a
OutOfMemoryError in all running threads. I changed the vm to run with -mx50m
and it ran for much longer (about 5 days) then it too did the same thing.
Currently I am trying to add some sort of alert before it runs out of memory,
mostly for debugging purposes, but it seems like the set of methods to access
memory do not take into account the maximum limits passed in via -mx. I can
see that this is a good thing, because I could tell it that it has some insane
amount of memory when it really has a few megs... but is there a happy medium?
If anyone has run into memory problems and found suitable solutions I would
like to hear about them.
