Re: gzip on mac ox s mountain lion hangs on NAS

[Welsh, Robert]

it just kept running on and on, but I'd suspect it's the

open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17


that is failing, but gzip just keeps trying and unless I hit ctrl-c it
just keeps spitting out that error above.

when I do hit ctrl-c it finishes with:

open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17
open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17
open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17
open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17
open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17
open("dtruss-test.txt.gz\0", 0x801, 0x81ED)              = -1 Err#17

Sorry, I don't understand this output.  Does the "^C" mean
that you typed control-C?  If so, why did gzip continue?
It's supposed to exit if you interrupt it.  Nor do I understand
why gzip would open dtruss-test.txt more than once, or what
that __mac_syscall means.  Perhaps you can find an OS X expert
who can decipher this dtruss output.
