Memory issues writing binary files, using a subVI to do all File Handling, topVI, when run normally files are way too large.

[Waltz]

Problem writing binary files with LV 8.5. I have one VI that does all the interaction/file I/O and another VI for testing. I find when I run the subVI where all the data reading/writing is happening with break points and single stepping through the code all is OK, but when I run normally the files are much larger than they should be and as well when I close the files I get a error. Any insights?

Can you be more specific?  What errors do you see?  Can you share your code?

[Yamaeda]

Sounds like you have some fast spinning loop in your sub-vi writing way too much.

I have been called out of town, will tidy up code and post when I get back.

I found the problem, I was actually trying to close the files twice.

Thanks

I don't see how this could cause the symptoms you described in the first post.

(It only explains the error on close).
