Informix Error -3680: PERFORM has run out of memory.

Reasons / Common Causes

-3680 fires when PERFORM can't obtain the memory data space it needs at runtime — per the official guidance, this is a memory-exhaustion condition requiring the form to be simplified.

1. A form too complex for PERFORM's available memory at runtime, per the official guidance — the direct, only cause.

Solutions / Resolution

1. Reduce the complexity of the form, per the official guidance.

Examples

Simplifying a memory-heavy form

Split a very large or heavily-joined form into smaller forms, or reduce the number of fields, screens, and joined tables involved, following the same approach as for -2988's compile-time memory exhaustion.

Diagnostic Checks

1. Check the overall size and complexity of the form, and simplify it if PERFORM reports running out of memory.
