"Bad Address" error from random executables causing freezes after "upgrading" to Win7

"Bad Address" error from random executables causing freezes after "upgrading" to Win7

[Wayne Hayes]

Folks,

I recently upgraded to Windows 7.  Before that I was running XP with Cygwin 5.1.
(I can't give you the exact version because it's now gone).  I have scripts
running in the background constantly doing things like downloading news, uploading
my current dynamic IP to another machine, running a nigthly unison, etc.  Immediately
after upgrading to Windows 7, I started seeing very infrequent errors like the following:

    [... a few minutes of execution without errors ...]
    /home/wayne/bin/quote: line 8: /usr/bin/date: Bad address
    [... a few more minutes of execution without errors ... ]
    /home/wayne/bin/quote: line 74: /usr/bin/tr: Bad address
    [... a few more minutes of execution without errors ... ]
    bash: /home/wayne/bin/quote: /bin/sh: bad interpreter: Bad address
    /home/wayne/bin/quote: fork: Resource temporarily unavailable
    /home/wayne/bin/quote: fork: Resource temporarily unavailable
    /home/wayne/bin/quote: fork: Resource temporarily unavailable
    /home/wayne/bin/quote: fork: Resource temporarily unavailable

Note that the error is coming from random executables called from my scripts.
Now, the "fork: Resource temporarily unavaible" errors I've seen before, ongoing
for years, and they're annoying but not critical because execution would always
continue.  I would also consider these "Bad address" errors not to be crucial except
occasionally they cause my script to just freeze up and stop dead.  Not good since
I need these scripts to be running continuously.

The first thing I did was upgrade from Cygwin 5.1 to 6.1, the most recent stable
release.  It didn't solve the problem.  Then I tried re-compiling all my own personal
executables.  No luck.  Then I found a description of a similar problem back in
August on this list,

    http://cygwin.com/ml/cygwin/2010-08/msg00277.html

where Corinna Vinschen suggested getting the most recent developer version.  I
assumed this means cygwin1.dll.  So I went and got the most recent developer
version, which is 13 February 2011, and I downloaded and un-tar'd

    http://cygwin.org/snapshots/cygwin-inst-20110213.tar.bz2

Then I rebooted.  No luck.  The problem persists.

This is what "uname -a" now says:

    CYGWIN_NT-6.1 pisa 1.7.8s(0.236/5/3) 20110213 16:43:51 i686 Cygwin

Has anybody else encountered this problem?  Any clue as to what's causing it?

Hi Wayne,
    I've been getting numerous "Bad address" errors on an upgraded
Cygwin installation (from 1.5 to 1.7).

    Have no clue what is causing the problem and have tried everything I
could think of to try and get rid of it to no avail.

    I have started several different threads in the past couple weeks
that one way or the other deal with the issue.

    Try searching the archive for them.

    Sample topic:
        1.7.7: Windows 2003 R2 WOW64: Cygwin installation fails

    Good luck.


Regards,
Gerry
