Informix Error -4122: Parser limitations have been exceeded. Try to reduce complexity or size of module.
Cause and resolution
Parser limitations have been exceeded. Try to reduce complexity or size of module.
The parser has returned an error that is NOT a syntax error. This error could be caused by a parser-stack overflow (too many levels of nesting within IF statements, WHILE statements, or the like) or by the parser running out of parser-stack space (the module is too large). Try to reduce the complexity of the code by splitting complex functions into multiple functions or splitting the module into multiple modules.
Oninit® Troubleshooting Guidance
Reasons / Common Causes
-4122 fires when the parser hits an internal limitation that isn't a syntax error — per the
official guidance, this can be a parser-stack overflow (too many nesting levels in IF,
WHILE, etc.) or the parser running out of stack space because the module is too large.
- Excessive nesting depth (in
IF,WHILE, or similar constructs), per the official guidance — the first named cause. - A module too large for the parser's available stack space, per the official guidance — the second named cause.
Solutions / Resolution
- Split complex functions into multiple functions, per the official guidance.
- Split the module into multiple modules, per the official guidance.
Examples
Reducing nesting depth
Break a deeply nested chain of IF/WHILE statements into smaller functions, each handling
one level of logic, rather than nesting everything in a single function body.
Diagnostic Checks
- Check the source for unusually deep nesting or an unusually large single module, and split it accordingly.
