When I try to run Cygwin Setup, it hangs, as far as I can make out,
forever.
This behaviour occurs in all of the following four circumstances:
1 An "install from internet" update of an existing Cygwin
installation, which consisted of the default packages, plus a few
extra.
2 A fresh "install from internet," after deleting my existing
Cygwin installation, with all packages marked for installation.
3 A fresh "install from local directory," after deleting my
existing Cygwin installation, with all packages marked for
installation.
4 A fresh "install from local directory," after deleting my
existing Cygwin installation, with the default set of packages
marked for installation.
The stage, at which the hang occurs, is after downloading/MD5sum
checking is complete, and during installation of the first package
(a2ps in cases 1-3, ash in case 4.) I note that this is the same
stage where McAfee and Norton anti-viruses are [Cygwin FAQ] believed
to lead to similar behaviour, so I stopped (unloaded, in its own
terms) my anti-virus (F-Secure,) and tried 2 and 3 again (this is the
only way I tried 4.) I observed the same behaviour.
Keeping Windows Task Manager's "Processes" tab open while running
Cygwin Setup (case 2, with anti-virus unloaded) allows monitoring of
memory usage. The following statistics are in kB.
Memory Usage
By What? setup.exe other processes total
When?
At start of 28872 ~69000 172104
download
At end of 4604 ~33000 ~ 177000
download/
start of
install
Immediately 31828 ~25000 ~ 605000
before
aborting
install with
"Cancel"
button (~40
minutes
after start
of install)
Immediately 64000 ~16000 ~ 650000
after
aborting
install
Immediately ~60000 Not noted ~1050000
before
setup.exe
disappears
from process
list (~10
minutes after
aborting)
Immediately n/a ~26000 ~156000
after
setup.exe
disappears
from process
list
This sounds like a memory leak, either in setup.exe, or related to
setup.exe, to me. Either way, it's left me without Cygwin :-(.
The listed processes' memory use does not add up to the total memory
use, as previously noted [S. Reddie. Memory leak? (was: 1.3.9: "fork:
Permission denied" (Windows 2000.)) [EMAIL PROTECTED], Feb. 2002.], in
a rather different context, on this mailing list.
Any ideas, please, anyone?
