[Mono-dev] SGen stability

[Roope Kangas]

Hi!

I am working on a MMO game thats written in C#. We are currently running load tests on mono 3.0.0 in linux environment.

I have noticed a few times that when we cause a spike the amount of threads we run the server sometimes crashes with the following output:

Native stacktrace:

        mono-sgen() [0x498441]
        mono-sgen() [0x4ec2df]
        mono-sgen() [0x41c217]
        /lib64/libpthread.so.0(+0xf500) [0x7fd5a1257500]
        mono-sgen(mono_class_is_assignable_from+0x30) [0x4ff070]
        mono-sgen(mono_object_isinst+0x3d) [0x57033d]
        mono-sgen() [0x463c88]
        [0x40216c3e]

Debug info from gdb:


=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

 Any ideas on what to do? This kind of behaviour does not occur with Boehm GC.
