Command swap -s is showing unexpected output for Solaris 10 (Doc ID 2494314.1)

Last updated on AUGUST 18, 2019

Applies to:

Solaris Operating System - Version 10 1/13 U11 to 10 1/13 U11 [Release 10.0]
Oracle Solaris on SPARC (64-bit)
Swap -s command is showing wrong output

bash-3.2# swap -s
total: 54325336k bytes allocated + 18446744073668361992k reserved = 13135712k used, 140041808k available

- Number of kb reserved is enormous and obviously not true. (18446744073668361992k )
- Swap space used is smaller then allocated. From what I know used swap space equals allocated + reserved.
