Event Viewer System.ArgumentNullException Errors

hello all
when i look at the event viewer on our server, I see a lot of error messages exactly the same as below.
I could not make anything of it. what does that mean? how should i proceed?
I have many web service calls but none of them has such a null input problem.

Might not be same problem but we had similar error message today.

Problem was that Dynamics NAV 2009 R2 RTC crashed when trying to add Columns to Page by right clicking the column fields.
This was solved removing unfinished field from Page object.

Odd with this was that the page compiled even the field was not bound to table field.

Anyways, I hope this helps someone. Odd bug for sure.
