segkpsize (Solaris 7 and Earlier Releases)

Description

Specify the amount of kernel pageable memory available. This memory is used primarily for kernel thread stacks. Increasing this number allows either larger stacks for the same number of threads or more threads. This parameter can only be set on 64–bit kernels. 64-bit kernels use a default stack size of 24 Kbytes.

Available for the Solaris 7 release with patch 106541-04 or the Solaris 7 5/99 and Solaris 8 releases.
