Error 8 occurred at Bus error: an error counter reached the "heavy"/"warning" limit

[sasimitha]

I am getting the following error in LabVIEW. Kindly support me to solve this issue.

Error 8 occurred at Bus error: an error counter reached the "heavy"/"warning" limit

Possible reason(s):

LabVIEW: (Hex 0x8) File permission error. You do not have the correct permissions for the file.
===========================
DMA hardware error detected.

Hi sasimitha,

mind to share more information about that error?

• When/where does the error occur?
• Is it related to any hardware or do you try to access files without permissions?

Google says its about PCAN. Maybe start here:

(I've posted this almost exactly before, posting it again now...)

In the olden days of LabVIEW, pre-2000, they developed the current error system but didn't quite think it all the way through.  So when they started making error codes, they just started counting up from 1 every time they needed a new one.  Problem is, they weren't the only people to do this.  So any very low-numbered error code can have multiple meanings.

In an effort to be "helpful", if any code generates an error number, LabVIEW will look it up in its table and give you what it sees there, which can be misleading for lower numbers.

Error 8 can mean:

Permissions error when trying to open a file or directory

Generic problem with DMA hardware

Any one of thousands of DLLs or user-created code has put error 8 on the error chain

It's almost certainly that last one.  Thols is probably on the right track with the Google search result, but yes, we need more details.
