Release 10.1A: OpenEdge Deployment:
Startup Command and Parameter Reference

Stack Size (-s)

Use Stack Size (-s) to change the size of the stack (an internal memory area used by Progress program modules).

Operating system and syntax	UNIX Windows	-s n
Use with	Maximum value	Minimum value	Single-user default	Multi-user default
Client Session	5,242,8781	9	40	40

1Actual maximum value is limited only by available memory

n

The size of the stack in 1KB units.

Note: It is recommended that the -s session startup parameter be set to 128. Setting this startup parameter to a smaller value may result in runtime errors in some environments.

Increase the stack size if one of the following messages appears:

SYSTEM ERROR: stkpush: stack overflow. Increase -s parameter. SYSTEM ERROR: stkditem: stack overflow. Increase -s parameter.

Stack overflow errors are most likely when data definitions are loaded for very large tables or use recursive procedures.

Note: If your application passes array parameters to procedures or functions, your stack size requirements can increase significantly.
