Informix Error -1162

Reasons / Common Causes

-1162 fires when FMP (IBM Informix 4GL/RF) has reached its limit on the number of forms that can be open concurrently — per the official guidance, this is a platform-specific concurrency limit, the same general family as -1159/-1160's concurrent-statement limits, but for open forms.

1. The number of concurrently open forms 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.
2. Close forms that aren't actively needed, as a practical first step, given the concurrency- limit framing shared with -1159/-1160.

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 forms are concurrently open against FMP's configured limit, per the installation documentation for the platform in use.

• -1158 — "FMP has run out of memory." A related FMP resource-limit error, about raw memory rather than open-form count.
• -1159 — "FMP has exceeded its number of concurrent INPUT statements." A related FMP concurrent-limit error, for INPUT statements rather than open forms.
• -1160 — "FMP has exceeded its number of concurrent DISPLAY ARRAY statements." Another related FMP concurrent-limit error.

FMP's concurrently-open-forms limit was exceeded — close unneeded forms and consult the installation documentation for the platform in use.
