Hi Alexander,
I have traced through my code thoroughly and there
is no memory leak. I
have also printed the Garbage Collector's output. The
heap used never goes
beyond 1 Mb (I tried with setting the initial heap
size as well but no
solution). Also i read about the stack size per thread
and set that as well
to 128kb (solaris has 512 kb.. and i don't know
default value for linux).
But still it gave the same error.
Can you tell me whether green threads can solve my
problem? Can
Blackdown porting help me?
