> Unfortunately I can't debug it. As I have already written in my previous email the program is executed on several clusters and each of them contains a lot of computers. This error occurs only on several nodes and every time these nodes are different (they are even located on different clusters)... I don't know how to make distributed debugging with GDB (and not sure that it is possible). Is it possible to add some null-checkings in method GetSerializationCallbacks? For example, like this:

In metadata/object.c move the line:
	vt->type = mono_type_get_object (domain, &class->byval_arg);
	mono_domain_unlock (domain);

and see if you can reproduce.
