May be an EMC issue.
Would need a lot more information to find root cause.
Details would include schematics, application information, operating environment, etc.

From what I've red, the pull up needs to be 10k and pulled up to 3.3v, if 5v a level shifter is needed?But more info on circuit, would help.
