It seems many, like me, use custom functions that return a table name or an unqualified field name. I bet many, like me, use GetFieldName with these functions. I suggest you read the following post: [Out of Memory Error](https://the.fmsoup.org/t/out-of-memory-error/3100). GetFieldName seems to have an unfortunate caveat.

Hope this helps.
