Re: Memory leak in Solaris 2.7 kernel?

["Thomas J. Arseneault" <arsen () CERTAINTYSOLUTIONS COM>]

I got the same results as the original poster on Solaris 2.6 (a sparc 2 with
32Mb memory, yes I know its a wimp) and the same as Jason on a Linux system
(Redhad 6.2, with 128Mb). On the Sol.2.6 system it would run until it gets
a:

# ls ../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*
no stack space
# uptime
cannot fork: no swap space

and it required a reboot to free it up. But only as root, as a normal user I
got the same as the linux system (which was the same as either root or a
reqular user).

# ls ../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*/../*
/bin/ls: Argument list too long.
#  uptime
 10:09pm  up 9 days,  5:46,  2 users,  load average: 0.05, 0.03, 0.01

Just two more data points.
