Informix Error -1211

Reasons / Common Causes

-1211 fires when 4GL can't allocate memory for a small, temporary work area used to process an expression — per the official guidance, this is a general memory-pressure condition at expression-evaluation time.

1. Overall memory pressure on the running program, per the official guidance — too many windows, variables, or other consumers leaving too little for this temporary work area.
2. A particularly complex expression requiring more temporary working space than a simpler one would.

Solutions / Resolution

1. Simplify the program to free up sufficient memory, per the official guidance — reduce open windows, global variables, or other memory consumers.
2. Simplify the specific expression involved, if it's unusually complex, breaking it into smaller intermediate steps.

Examples

Breaking a complex expression into steps

LET v_step1 = a + b * c;
LET v_step2 = v_step1 / d - e;
LET v_result = v_step2 * f;
-- instead of one large combined expression

Diagnostic Checks

1. Review overall memory usage (open windows, global variables) for opportunities to simplify.
2. Identify the specific expression that failed, and consider breaking it into smaller pieces.

Insufficient memory for a temporary expression work area — reduce overall memory usage, and simplify the specific expression if it's unusually complex.
