I tested the new version of Mono 3.2 using the sgen GC. I still have the same problem: every new thread uses a bit more than 64MB or RAM on Linux. So, in my virtual environment limited to 512MB of (virtual) RAM, it crashes (stops silently with a return code equals to 1) when I try to create my 6th thread.
I tested the same program on Windows 7 with a MS .Net environment. I started 1000 threads and my program only used 48MB of RAM. I did not try to create more threads because I would have to create millions of thread to each a problem. I am really not doing some strange operations, just create threads in a loop, with a pause of 1 sec between each one to let me time to see how munch memory is consumed. Am I the only one who encounter this strange behavior with thread of 64MB or is it considered as normal?
