Unable to find root cause of ArgumentException

I'm investigating the cause of the huge amount of ArgumentException in an application (and I'm suspecting that its main reason for memory fragmentation/out of memory exception). The problem is that I can't find where this exception is coming from.

I have memory dump of the problematic service but all I can see is that it happened on one of the threads and that it is related to reflection stuff, other than that it seems that I can't find the cause of the exception.

ArgumentException details:

Exception type:   System.ArgumentException
Message:          Missing parameter does not have a default value.
InnerException:   <none>
StackTrace (generated):
    SP       IP       Function

Output of ~#s; !clrstack:

How to find out where this exception came from? It looks like its missing part of the stack trace.

According to the Microsoft documentation, The PropertyInfo.GetValue() method throws an ArgumentException when either of the following is true:

"The index array does not contain the type of arguments needed.

-or-

The property's get accessor is not found."

I would look for any calls in the source code that are calling GetValue() and inspect the arguments being passed into them. One of the two scenarios outlined above is likely the culprit.
