Let thread wait till memory is available

hi all,
a basic question:

i have a memory consuming encoding process which runs in its own
thread.

To preseve OutOfMemory errors when a lot of those treads are running,
i want this thread to check the current memory heap, and maybe wait as
long as there's some available.

Is that possible ?
I think this must be a very common problem in thread programming?

Greets,
chris

You may take a look at java.lang.Runtime.free/max/totalMemory.

Hth,

Other options are to start and catch any OOM errors. Or use a thread
pool with limited size to limit concurrent processing.

Kind regards

But that might crash other threads (with low mem usage) with an OOME as
well!

OK.
