LabView PDA module gives error "unable to lock memory chunk"

I've written a LabVIEW PDA Application that reads an ASCII decimal string through a PDA serial port. I can display the string ok, but when I try to convert the string to a number using the decimal string to number VI I get the error message "App failed. Error Code 172649003. Unable to lock memory chunk."
Any ideas?

Does this happen whenever you use the string to number VI (can you reproduce this in an empty VI)?
Are you sure it happened because of that VI and not because of something else that is happening in the VI at the same time?
Can you cut down pieces of the code and still get the error? Can you post a small example?
Which PDA\LV are you using?
Can you write some more details about your app (does it do anything else other than serial comm)?
