Two types of memory issues

Hi all!

I'm creating an app which is constantly creating worker-threads (as many as
possible) using lots of CPU and heaps of memory allocations.

I have a AMD64bit server with 32GB RAM and 8 cores which it runs on. The
program is compiled in .Visual Studio Express on Win64, copied to the server
running mono 2.0.1  (C#)

After running a few hours I seem to constantly be running into the same
memory issues, which I believe is with the garbage collector or the
configuration of it. When it crashes it usually has a

Error 1)
"Too many heap sections: Increase MAXHINCR or MAX_HEAP_SECTS"
This error usually seems to be associated with the StringBuilder class, and
I have managed to overcome a few of the instances where it crashes by
avoiding to use StringBuilder.

So, how do i Increase MAXINCHR and/or MAX_HEAP_SECTS? -And will this be a
finite solution?

Error 2)
mmap(...PROT_NONE...) failed
Stacktrace:
  at (wrapper managed-to-native)
System.Object.__icall_wrapper_mono_object_new_f                 ast (intptr)

  at (wrapper managed-to-native)
System.Object.__icall_wrapper_mono_object_new_f                 ast (intptr)

followed by


Native stacktrace:

        mono [0x428742]
        /usr/app/glibc/current/lib/libpthread.so.0 [0x7fb65b81d4b0]
        /usr/app/glibc/current/lib/libc.so.6(gsignal+0x3b) [0x7fb65b279ffb]
        /usr/app/glibc/current/lib/libc.so.6(abort+0x110) [0x7fb65b27b4e0]


Any ideas on this one?

Thanx,

jornare
