Error:Null in Custom Text Area

Error:Null in Custom Text Area

Currently have eleven (11) custom fields of type Text Area.  One particular Text Area field only allows 132 characters.  The addition of characters results in Error:Null.  For testing I have the same exact paragraph (964 characters) in the other 10 Text Area fields and the first 132 of 964 in the field of concern. As a result it does not seem to be a special character issue.

I thought it might be an overall record size issue but I can append additional characters to the other 10 Text Area fields without any problems.  The culprit field simply will not go beyond 132.

Thx
