should I be concerned about this error?

No. Not every failing system call is indicative of a problem. In fact, it's pretty normal to see many system calls return with an error code.  In many cases it's faster/easier/the-only-way to just make the call and react appropriately, rather than trying to determine beforehand whether the call would fail... (it's kinda like simply asking the question, instead of "May I ask a question?", followed by the question if you get "Yes" :)
