How to tune NCALL (kernel callout table size) in SCO?

On our production SCO OpenServer 5.0.5 system, I see this console message every few days:
"CONFIG: timeout - Timeout table free list empty (min_free_callouts = 50 exceeded)".

According to an entry in www.aplawrence.com/SCOFAQ/scotec1.html, if I read it correctly, this indicates that the NCALL kernel parameter value should be increased. I've stepped through every area (performance and configuration tunables) available in scoadmin, but I don't see the NCALL parameter listed.

How do I update this value?

Thanks!

NCALL is a kernel parameter that pertains to a release prior to SCO OpenServer 5 (SCO UNIX System V/386 Version 4.x). In SCO OpenServer 5, it has been replaced by MAXCALL. This parameter is not configurable. It has been set to a maximum of 5000, which is the maximum number of pending callouts.
