Informix Error -1159

Reasons / Common Causes

-1159 fires when FMP (IBM Informix 4GL/RF) has reached its limit on the number of simultaneous INPUT statements it can process concurrently — per the official guidance, this is a platform- specific concurrency limit.

1. The number of concurrently active INPUT statements exceeding FMP's configured limit, per the official guidance — no further application-level detail is given beyond directing to the installation documentation.

Solutions / Resolution

1. Consult the installation documentation for your system, per the official guidance, for guidance on resolving this constraint.

Examples

N/A

No specific triggering statement is documented — this is a platform-level concurrency limit for the FMP (4GL/RF) runtime.

Diagnostic Checks

1. Check how many INPUT statements are concurrently active against FMP's configured limit, per the installation documentation for the platform in use.
