Device (37, 0) is pms0 under NetBSD/i386, it may not be even
assigned under sgimips. Thus, the /emul/irix/dev/zero device
you created was most definitely not okay; if you really feel
you need it, it should be softlinked to NetBSD /dev/zero.

Are your process limits bumped high enough? What does
ktrace of the binary reveal?
