DOCUMENT ID: 1282-02

SYNOPSIS:    Swap space and tmp

OS RELEASE:  2.1, 2.3, 2.4

PRODUCT:     Solaris x86

KEYWORDS:    core dump swap space


SYMPTOMS:

Adding more swap space using "swap -a" doesn't always solve problem


DESCRIPTION:

Solaris as shipped allows tmp and swap to share space.  The relationship
of disk space utilization is not often clear.  The use of tmp "robs"
swap space and the use of swap robs tmp space.  In many situations a
system will run out of tmp space first and manafest a shortage of swap
space.  Other strange system behavior i.e.  core dumps in addition to
swap and tmp errors. 


SOLUTION:

In addition to adding more swap space tmp must be moved to some other
location.  This can be done by editing /etc/vfstab, the location where
both tmp and alternate swap are specified.
